Documentation/driver-api: fixed spelling mistakes
Fixed some spelling mistakes identified by misspell tool. The example code in Documentation/driver-api/nvdimm/nvdimm.rst contained a misspelled identifier (paramaters instead of parameters).

driver core: add a faux bus for use when a simple device/bus is needed
Many drivers abuse the platform driver/bus system as it provides a simple way to create and bind a device to a driver-specific set of probe/release functions. Instead of doing that, and wasting all of the memory associated with a platform device, here is a "faux" bus that can be used instead.

Char/Misc/IIO driver updates for 6.14-rc1
Here is the "big" set of char/misc/iio and other smaller driver
subsystem updates for 6.14-rc1. Loads of different things in here this
development cycle, highlights are:
- ntsync "driver" to handle Windows locking types enabling Wine to
work much better on many workloads (i.e. games). The driver
framework was in 6.13, but now it's enabled and fully working
properly. Should make many SteamOS users happy. Even comes with
tests!
- Large IIO driver updates and bugfixes
- FPGA driver updates
- Coresight driver updates
- MHI driver updates
- PPS driver updatesa
- const bin_attribute reworking for many drivers
- binder driver updates
- smaller driver updates and fixes
All of these have been in linux-next for a while with no reported
issues.

This happens because the only async polling without interrupts that
iaa_crypto currently implements is with the 'sync' mode. With 'async',
iaa_crypto calls to compress/decompress submit the descriptor and return
-EINPROGRESS, without any mechanism in the driver to poll for
completions. Hence callers such as test_acomp() in crypto/testmgr.c or
zswap, that wrap the calls to crypto_acomp_compress() and
crypto_acomp_decompress() in synchronous wrappers, will block
indefinitely. Even before zswap can notice this problem, the crypto
testmgr.c's test_acomp() will fail and prevent registration of
"deflate-iaa" as a valid crypto acomp algorithm, thereby disallowing the
use of "deflate-iaa" as a zswap compress (zswap will fall-back to the
default compressor in this case).
To fix this issue, this patch modifies the iaa_crypto sync_mode set
function to treat 'async' equivalent to 'sync', so that the correct and
only supported driver async polling without interrupts implementation is
enabled, and zswap can use 'deflate-iaa' as the compressor.
Hence, with this patch, this is what will happen:
echo async > /sys/bus/dsa/drivers/crypto/sync_mode
cat /sys/bus/dsa/drivers/crypto/sync_mode
sync
There are no crypto/testmgr.c test_acomp() errors, no call traces and zswap
can use 'deflate-iaa' without any errors. The iaa_crypto documentation has
also been updated to mention this caveat with 'async' and what to expect
with this fix.
True iaa_crypto async polling without interrupts is enabled in patch
"crypto: iaa - Implement batch_compress(), batch_decompress() API in
iaa_crypto." [1] which is under review as part of the "zswap IAA compress
batching" patch-series [2]. Until this is merged, we would appreciate it if
this current patch can be considered for a hotfix.

Driver core changes for 6.13-rc1
Here is a small set of driver core changes for 6.13-rc1.
Nothing major for this merge cycle, except for the 2 simple merge
conflicts are here just to make life interesting.
Included in here are:
- sysfs core changes and preparations for more sysfs api cleanups that
can come through all driver trees after -rc1 is out
- fw_devlink fixes based on many reports and debugging sessions
- list_for_each_reverse() removal, no one was using it!
- last-minute seq_printf() format string bug found and fixed in many
drivers all at once.
- minor bugfixes and changes full details in the shortlog
As mentioned above, there is 2 merge conflicts with your tree, one is
where the file is removed (easy enough to resolve), the second is a
build time error, that has been found in linux-next and the fix can be
seen here:
https://lore.kernel.org/r/20241107212645.41252436@canb.auug.org.au
Other than that, the changes here have been in linux-next with no other
reported issues.

Merge tag 'pci-v6.13-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci
Pull PCI updates from Bjorn Helgaas:
"Enumeration:
- Make pci_stop_dev() and pci_destroy_dev() safe so concurrent
callers can't stop a device multiple times, even as we migrate from
the global pci_rescan_remove_lock to finer-grained locking (Keith
Busch)
- Improve pci_walk_bus() implementation by making it recursive and
moving locking up to avoid need for a 'locked' parameter (Keith
Busch)
- Unexport pci_walk_bus_locked(), which is only used internally by
the PCI core (Keith Busch)
- Detect some Thunderbolt chips that are built-in and hence
'trustworthy' by a heuristic since the 'ExternalFacingPort' and
'usb4-host-interface' ACPI properties are not quite enough (Esther
Shimanovich)
Resource management:
- Use PCI bus addresses (not CPU addresses) in 'ranges' properties
when building dynamic DT nodes so systems where PCI and CPU
addresses differ work correctly (Andrea della Porta)
- Tidy resource sizing and assignment with helpers to reduce
redundancy (Ilpo Järvinen)
- Improve pdev_sort_resources() 'bogus alignment' warning to be more
specific (Ilpo Järvinen)
Driver binding:
- Convert driver .remove_new() callbacks to .remove() again to finish
the conversion from returning 'int' to being 'void' (Sergio
Paracuellos)
- Export pcim_request_all_regions(), a managed interface to request
all BARs (Philipp Stanner)
- Replace pcim_iomap_regions_request_all() with
pcim_request_all_regions(), and pcim_iomap_table()[n] with
pcim_iomap(n), in the following drivers: ahci, crypto qat, crypto
octeontx2, intel_th, iwlwifi, ntb idt, serial rp2, ALSA korg1212
(Philipp Stanner)
- Remove the now unused pcim_iomap_regions_request_all() (Philipp
Stanner)
- Export pcim_iounmap_region(), a managed interface to unmap and
release a PCI BAR (Philipp Stanner)
- Replace pcim_iomap_regions(mask) with pcim_iomap_region(n), and
pcim_iounmap_regions(mask) with pcim_iounmap_region(n), in the
following drivers: fpga dfl-pci, block mtip32xx, gpio-merrifield,
cavium (Philipp Stanner)
Error handling:
- Add sysfs 'reset_subordinate' to reset the entire hierarchy below a
bridge; previously Secondary Bus Reset could only be used when
there was a single device below a bridge (Keith Busch)
- Warn if we reset a running device where the driver didn't register
pci_error_handlers notification callbacks (Keith Busch)
ASPM:
- Disable ASPM L1 before touching L1 PM Substates to follow the spec
closer and avoid a CPU load timeout on some platforms (Ajay
Agarwal)
- Set devices below Intel VMD to D0 before enabling ASPM L1 Substates
as required per spec for all L1 Substates changes (Jian-Hong Pan)
Power management:
- Enable starfive controller runtime PM before probing host bridge
(Mayank Rana)
- Enable runtime power management for host bridges (Krishna chaitanya
chundru)
Power control:
- Use of_platform_device_create() instead of of_platform_populate()
to create pwrctl platform devices so we can control it based on the
child nodes (Manivannan Sadhasivam)
- Create pwrctrl platform devices only if there's a relevant power
supply property (Manivannan Sadhasivam)
- Add device link from the pwrctl supplier to the PCI dev to ensure
pwrctl drivers are probed before the PCI dev driver; this avoids a
race where pwrctl could change device power state while the PCI
driver was active (Manivannan Sadhasivam)
- Find pwrctl device for removal with of_find_device_by_node()
instead of searching all children of the parent (Manivannan
Sadhasivam)
- Rename 'pwrctl' to 'pwrctrl' to match new bandwidth controller
('bwctrl') and hotplug files (Bjorn Helgaas)
Bandwidth control:
- Add read/modify/write locking for Link Control 2, which is used to
manage Link speed (Ilpo Järvinen)
- Extract Link Bandwidth Management Status check into
pcie_lbms_seen(), where it can be shared between the bandwidth
controller and quirks that use it to help retrain failed links
(Ilpo Järvinen)
- Re-add Link Bandwidth notification support with updates to address
the reasons it was previously reverted (Alexandru Gagniuc, Ilpo
Järvinen)
- Add pcie_set_target_speed() and related functionality so drivers
can manage PCIe Link speed based on thermal or other constraints
(Ilpo Järvinen)
- Add a thermal cooling driver to throttle PCIe Links via the
existing thermal management framework (Ilpo Järvinen)
- Add a userspace selftest for the PCIe bandwidth controller (Ilpo
Järvinen)
PCI device hotplug:
- Add hotplug controller driver for Marvell OCTEON multi-function
device where function 0 has a management console interface to
enable/disable and provision various personalities for the other
functions (Shijith Thotton)
- Retain a reference to the pci_bus for the lifetime of a pci_slot to
avoid a use-after-free when the thunderbolt driver resets USB4 host
routers on boot, causing hotplug remove/add of downstream docks or
other devices (Lukas Wunner)
- Remove unused cpcihp struct cpci_hp_controller_ops.hardware_test
(Guilherme Giacomo Simoes)
- Remove unused cpqphp struct ctrl_dbg.ctrl (Christophe JAILLET)
- Use pci_bus_read_dev_vendor_id() instead of hand-coded presence
detection in cpqphp (Ilpo Järvinen)
- Simplify cpqphp enumeration, which is already simple-minded and
doesn't handle devices below hot-added bridges (Ilpo Järvinen)
Virtualization:
- Add ACS quirk for Wangxun FF5xxx NICs, which don't advertise an ACS
capability but do isolate functions as though PCI_ACS_RR and
PCI_ACS_CR were set, so the functions can be in independent IOMMU
groups (Mengyuan Lou)
TLP Processing Hints (TPH):
- Add and document TLP Processing Hints (TPH) support so drivers can
enable and disable TPH and the kernel can save/restore TPH
configuration (Wei Huang)
- Add TPH Steering Tag support so drivers can retrieve Steering Tag
values associated with specific CPUs via an ACPI _DSM to improve
performance by directing DMA writes closer to their consumers (Wei
Huang)
Data Object Exchange (DOE):
- Wait up to 1 second for DOE Busy bit to clear before writing a
request to the mailbox to avoid failures if the mailbox is still
busy from a previous transfer (Gregory Price)
Endpoint framework:
- Skip attempts to allocate from endpoint controller memory window if
the requested size is larger than the window (Damien Le Moal)
- Add and document pci_epc_mem_map() and pci_epc_mem_unmap() to
handle controller-specific size and alignment constraints, and add
test cases to the endpoint test driver (Damien Le Moal)
- Implement dwc pci_epc_ops.align_addr() so pci_epc_mem_map() can
observe DWC-specific alignment requirements (Damien Le Moal)
- Synchronously cancel command handler work in endpoint test before
cleaning up DMA and BARs (Damien Le Moal)
- Respect endpoint page size in dw_pcie_ep_align_addr() (Niklas
Cassel)
- Use dw_pcie_ep_align_addr() in dw_pcie_ep_raise_msi_irq() and
dw_pcie_ep_raise_msix_irq() instead of open coding the equivalent
(Niklas Cassel)
- Avoid NULL dereference if Modem Host Interface Endpoint lacks
'mmio' DT property (Zhongqiu Han)
- Release PCI domain ID of Endpoint controller parent (not controller
itself) and before unregistering the controller, to avoid
use-after-free (Zijun Hu)
- Clear secondary (not primary) EPC in pci_epc_remove_epf() when
removing the secondary controller associated with an NTB (Zijun Hu)
Cadence PCIe controller driver:
- Lower severity of 'phy-names' message (Bartosz Wawrzyniak)
Freescale i.MX6 PCIe controller driver:
- Fix suspend/resume support on i.MX6QDL, which has a hardware
erratum that prevents use of L2 (Stefan Eichenberger)
Intel VMD host bridge driver:
- Add 0xb60b and 0xb06f Device IDs for client SKUs (Nirmal Patel)
MediaTek PCIe Gen3 controller driver:
- Update mediatek-gen3 DT binding to require the exact number of
clocks for each SoC (Fei Shao)
- Add support for DT 'max-link-speed' and 'num-lanes' properties to
restrict the link speed and width (AngeloGioacchino Del Regno)
Microchip PolarFlare PCIe controller driver:
- Add DT and driver support for using either of the two PolarFire
Root Ports (Conor Dooley)
NVIDIA Tegra194 PCIe controller driver:
- Move endpoint controller cleanups that depend on refclk from the
host to the notifier that tells us the host has deasserted PERST#,
when refclk should be valid (Manivannan Sadhasivam)
Qualcomm PCIe controller driver:
- Add qcom SAR2130P DT binding with an additional clock (Dmitry
Baryshkov)
- Enable MSI interrupts if 'global' IRQ is supported, since a
previous commit unintentionally masked them (Manivannan Sadhasivam)
- Move endpoint controller cleanups that depend on refclk from the
host to the notifier that tells us the host has deasserted PERST#,
when refclk should be valid (Manivannan Sadhasivam)
- Add DT binding and driver support for IPQ9574, with Synopsys IP
v5.80a and Qcom IP 1.27.0 (devi priya)
- Move the OPP "operating-points-v2" table from the
qcom,pcie-sm8450.yaml DT binding to qcom,pcie-common.yaml, where it
can be used by other Qcom platforms (Qiang Yu)
- Add 'global' SPI interrupt for events like link-up, link-down to
qcom,pcie-x1e80100 DT binding so we can start enumeration when the
link comes up (Qiang Yu)
- Disable ASPM L0s for qcom,pcie-x1e80100 since the PHY is not tuned
to support this (Qiang Yu)
- Add ops_1_21_0 for SC8280X family SoC, which doesn't use the
'iommu-map' DT property and doesn't need BDF-to-SID translation
(Qiang Yu)
Rockchip PCIe controller driver:
- Define ROCKCHIP_PCIE_AT_SIZE_ALIGN to replace magic 256 endpoint
.align value (Damien Le Moal)
- When unmapping an endpoint window, compute the region index instead
of searching for it, and verify that the address was mapped (Damien
Le Moal)
- When mapping an endpoint window, verify that the address hasn't
been mapped already (Damien Le Moal)
- Implement pci_epc_ops.align_addr() for rockchip-ep (Damien Le Moal)
- Fix MSI IRQ data mapping to observe the alignment constraint, which
fixes intermittent page faults in memcpy_toio() and memcpy_fromio()
(Damien Le Moal)
- Rename rockchip_pcie_parse_ep_dt() to
rockchip_pcie_ep_get_resources() for consistency with similar DT
interfaces (Damien Le Moal)
- Skip the unnecessary link train in rockchip_pcie_ep_probe() and do
it only in the endpoint start operation (Damien Le Moal)
- Implement pci_epc_ops.stop_link() to disable link training and
controller configuration (Damien Le Moal)
- Attempt link training at 5 GT/s when both partners support it
(Damien Le Moal)
- Add a handler for PERST# signal so we can detect host-initiated
resets and start link training after PERST# is deasserted (Damien
Le Moal)
Synopsys DesignWare PCIe controller driver:
- Clear outbound address on unmap so dw_pcie_find_index() won't match
an ATU index that was already unmapped (Damien Le Moal)
- Use of_property_present() instead of of_property_read_bool() when
testing for presence of non-boolean DT properties (Rob Herring)
- Advertise 1MB size if endpoint supports Resizable BARs, which was
inadvertently lost in v6.11 (Niklas Cassel)
TI J721E PCIe driver:
- Add PCIe support for J722S SoC (Siddharth Vadapalli)
- Delay PCIE_T_PVPERL_MS (100 ms), not just PCIE_T_PERST_CLK_US (100
us), before deasserting PERST# to ensure power and refclk are
stable (Siddharth Vadapalli)
TI Keystone PCIe controller driver:
- Set the 'ti,keystone-pcie' mode so v3.65a devices work in Root
Complex mode (Kishon Vijay Abraham I)
- Try to avoid unrecoverable SError for attempts to issue config
transactions when the link is down; this is racy but the best we
can do (Kishon Vijay Abraham I)
Miscellaneous:
- Reorganize kerneldoc parameter names to match order in function
signature (Julia Lawall)
- Fix sysfs reset_method_store() memory leak (Todd Kjos)
- Simplify pci_create_slot() (Ilpo Järvinen)

firewire updates for v6.12
The batch of changes includes the followwing:
- Replacing tasklet with usual workqueue for isochronous context
- Replacing IDR with XArray
- Utilizing guard macro where possible
- Printing deprecation warning when enabling debug parameter of
firewire-ohci module
Additionally, it includes a single patch for sound subsystem which the
subsystem maintainer acked:
- Switching to nonatomic PCM operation
In FireWire subsystem, tasklet has been used as the bottom half of 1394
OHCi hardIRQ so long. In the recent kernel updates, BH workqueue has
been available, and some developers have proposed replacing tasklet with
BH workqueue. While it is fortunate that developers are still considering
the legacy subsystem, a simple replacement is not necessarily suitable.
As a first step towards dropping tasklet, I've investigated the
feasibility for 1394 OHCI isochronous context, and concluded that usual
workqueue is available. In the context, the batch of packets is processed
in the specific queue, thus the timing jitter caused by task scheduling is
not so critical. Additionally, DMA transmission can be scheduled
per-packet basis, therefore the context can be sleep between the operation
of transmissions. Furthermore, in-kernel protocol implementation involves
some CPU-bound tasks, which can sometimes consumes CPU time so long. These
characteristics suggest that usual workqueue is suitable, through BH
workqueues are not.
The replacement with usual workqueue allows unit drivers to process the
content of packets in non-atomic context. It brings some reliefs to some
drivers in sound subsystem that spin-lock is not mandatory anymore during
isochronous packet processing.

"In the FireWire subsystem, tasklets have been used as the bottom half
of 1394 OHCi hardIRQ. In recent kernel updates, BH workqueues have
become available, and some developers have proposed replacing the

As a first step towards dropping tasklet use, the 1394 OHCI

Additionally, DMA transmission can be scheduled per-packet basis,

some CPU-bound tasks, which can sometimes consumes CPU time so long.
These characteristics suggest that normal workqueues are suitable,

The replacement with a workqueue allows unit drivers to process the

Pull thermal control updates from Rafael Wysocki:
"These mostly continue to rework the thermal core and the thermal zone
driver interface to make the code more straightforward and reduce
bloat
The most significant piece of this work is a change of the code
related to binding cooling devices to thermal zones which, among other
things, replaces two previously existing thermal zone operations with
one allowing driver implementations to be much simpler
There is also a new thermal core testing module allowing mock thermal
zones to be created and controlled via debugfs in order to exercise
the thermal core functionality. It is expected to be used for
implementing thermal core self tests in the future
Apart from the above, there are assorted thermal driver updates
Specifics:
- Update some thermal drivers to eliminate thermal_zone_get_trip()
calls from them and get rid of that function (Rafael Wysocki)

firewire: core: expose kernel API to schedule work item to process isochronous context
In packet-per-buffer mode for isochronous context of 1394 OHCI, software can schedule hardIRQ to the buffer in which the content of isochronous packet is processed. The actual behaviour is different between isochronous receive (IR) and transmit (IT) contexts in respect to isochronous cycle in which the hardIRQ occurs. In IR context, the hardIRQ occurs when the buffer is filled actually by the content of received packet. If there are any isochronous cycles in which the packet transmission is skipped, it is postponed to generate the hardIRQ in respect to the isochronous cycle. In IT context, software can schedule the content of packet every isochronous cycle including skipping, therefore the hardIRQ occurs in the isochronous cycle to which the software scheduled. ALSA firewire stack uses the packet-per-buffer mode for both IR/IT contexts. To process time stamp per packet (or per sample in some cases) steadily for media clock recovery against unexpected transmission skips, it uses an IT context to operate all of isochronous contexts by calls of fw_iso_context_flush_completions() in the bottom-half of hardIRQ for the IT context. Although it looks well to handle all of isochronous contexts in a single bottom-half context, it relatively takes longer time. In the future code integration (not yet), it is possible to apply parallelism method to process these context. In the case, it is useful to allow unit drivers to schedule work items to process these isochronous contexts. As a preparation, this commit exposes fw_iso_context_schedule_flush_completions() as a kernel API available by unit drivers. It is renamed from fw_iso_context_queue_work() since it is a counter part of fw_iso_context_flush_completions().

thermal: core: Drop unused bind/unbind functions and callbacks
There are no more callers of thermal_zone_bind_cooling_device() and thermal_zone_unbind_cooling_device(), so drop them along with all of the corresponding headers, code and documentation.

CXL for v6.11 merge window
New Changes:
- Refactor to a common struct for DRAM and general media CXL events
- Add abstract distance calculation support for CXL
- Add CXL maturity map documentation to detail current state of CXL enabling
- Add warning on mixed CXL VH and RCH/RCD hierachy to inform unsupported config
- Replace ENXIO with EBUSY for inject poison limit reached via debugfs
- Replace ENXIO with EBUSY for inject poison cxl-test support

Merge tag 'cxl-for-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl
Pull CXL updates from Dave Jiang:
"Core:
- A CXL maturity map has been added to the documentation to detail
the current state of CXL enabling.
It provides the status of the current state of various CXL features
to inform current and future contributors of where things are and
which areas need contribution.
- A notifier handler has been added in order for a newly created CXL
memory region to trigger the abstract distance metrics calculation.
This should bring parity for CXL memory to the same level vs
hotplugged DRAM for NUMA abstract distance calculation. The
abstract distance reflects relative performance used for memory
tiering handling.
- An addition for XOR math has been added to address the CXL DPA to
SPA translation.
CXL address translation did not support address interleave math
with XOR prior to this change.
Fixes:
- Fix to address race condition in the CXL memory hotplug notifier
- Add missing MODULE_DESCRIPTION() for CXL modules
- Fix incorrect vendor debug UUID define
Misc:
- A warning has been added to inform users of an unsupported
configuration when mixing CXL VH and RCH/RCD hierarchies
- The ENXIO error code has been replaced with EBUSY for inject poison
limit reached via debugfs and cxl-test support
- Moving the PCI config read in cxl_dvsec_rr_decode() to avoid
unnecessary PCI config reads
- A refactor to a common struct for DRAM and general media CXL

Nothing hugely exciting happening in the documentation tree this time
around, mostly more of the usual:
- More Spanish, Italian, and Chinese translations
- A new script, scripts/checktransupdate.py, can be used to see which
commits have touched an (English) document since a given translation was
last updated.
- A couple of "best practices" suggestions (on Link: tags and off-list
discussions) that were not entirely at consensus level, but I concluded
they were close enough to accept.
- Some nice cleanups removing documentation for kernel parameters that have
not been recognized for ... a long time.

spi: Updates for v6.11
There's some quite exciting core work in this release, we've got the
beginnings of support for hardware initiated transfers which is itself
independently useful for optimising fast paths in existing drivers.
We also have a rework of the DMA mapping which allows finer grained
decisions about DMA mapping messages and also helps remove some bodges
that we'd had.
Otherwise it's a fairly quiet release, a few new drivers and features
for existing drivers, together with various cleanups and DT binding
conversions.
One regmap SPI fix made it's way in here too which I should probably
have sent as a regmap fix instead.
- Support for pre-optimising messages, reducing the overhead for
messages that are repeatedly used (eg, reading the interrupt status
from a device). This will also be used for hardware initiated
transfers in future.
- A reworking of how DMA mapping is done, introducing a new helper and
allowing the DMA mapping decision to be done per transfer instead of
per message.
- Support for Atmel SAMA7D64, Freescale LX2160A DSPI and WCH CH341A.

gpio updates for v6.11-rc1
GPIOLIB core:
- rework kfifo handling rework in the character device code
- improve the labeling of GPIOs requested as interrupts and show more info
on interrupt-only GPIOs in debugfs
- remove unused APIs
- unexport interfaces that are only used from the core GPIO code
- drop the return value from gpiochip_set_desc_names() as it cannot fail
- move a string array definition out of a header and into a specific
compilation unit
- convert the last user of gpiochip_get_desc() other than GPIO core to using
a safer alternative
- use array_index_nospec() where applicable
New drivers:
- add a "virtual GPIO consumer" module that allows requesting GPIOs from actual
hardware and driving tests of the in-kernel GPIO API from user-space over
debugfs
- add a GPIO-based "sloppy" logic analyzer module useful for "first glance"
debugging on remote boards
Driver improvements:
- add support for a new model to gpio-pca953x
- lock GPIOs as interrupts in gpio-sim when the lines are requested as irqs
via the simulator domain + some other minor improvements
- improve error reporting in gpio-syscon
- convert gpio-ath79 to using dynamic GPIO base and range
- use pcibios_err_to_errno() for converting PCIBIOS error codes to errno
vaues in gpio-amd8111 and gpio-rdc321x
- allow building gpio-brcmstb for the BCM2835 architecture
DT bindings:
- convert DT bindings for lsi,zevio, mpc8xxx, and atmel to DT schema
- document new properties for aspeed,gpio, fsl,qoriq-gpio and gpio-vf610
- document new compatibles for pca953x and fsl,qoriq-gpio
Documentation:
- document stricter behavior of the GPIO character device uAPI with regards to
reconfiguring requested line without direction set

Merge tag 'gpio-updates-for-v6.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio updates from Bartosz Golaszewski:
"The majority of added lines are two new modules: the GPIO virtual
consumer module that improves our ability to add automated tests for
the kernel API and the "sloppy" logic analyzer module that uses the
GPIO API to implement a coarse-grained debugging tool for useful for
remote development.
Other than that we have the usual assortment of various driver
extensions, improvements to the core GPIO code, DT-bindings and other
documentation updates as well as an extension to the interrupt
simulator:
GPIOLIB core:
- rework kfifo handling rework in the character device code
- improve the labeling of GPIOs requested as interrupts and show more
info on interrupt-only GPIOs in debugfs
- remove unused APIs
- unexport interfaces that are only used from the core GPIO code
- drop the return value from gpiochip_set_desc_names() as it cannot
fail
- move a string array definition out of a header and into a specific
compilation unit
- convert the last user of gpiochip_get_desc() other than GPIO core
to using a safer alternative
- use array_index_nospec() where applicable
New drivers:
- add a "virtual GPIO consumer" module that allows requesting GPIOs
from actual hardware and driving tests of the in-kernel GPIO API
from user-space over debugfs
- add a GPIO-based "sloppy" logic analyzer module useful for "first
glance" debugging on remote boards
Driver improvements:
- add support for a new model to gpio-pca953x
- lock GPIOs as interrupts in gpio-sim when the lines are requested
as irqs via the simulator domain + some other minor improvements
- improve error reporting in gpio-syscon
- convert gpio-ath79 to using dynamic GPIO base and range
- use pcibios_err_to_errno() for converting PCIBIOS error codes to
errno vaues in gpio-amd8111 and gpio-rdc321x
- allow building gpio-brcmstb for the BCM2835 architecture
DT bindings:
- convert DT bindings for lsi,zevio, mpc8xxx, and atmel to DT schema
- document new properties for aspeed,gpio, fsl,qoriq-gpio and
gpio-vf610
- document new compatibles for pca953x and fsl,qoriq-gpio
Documentation:
- document stricter behavior of the GPIO character device uAPI with
regards to reconfiguring requested line without direction set
- clarify the effect of the active-low flag on line values and edges
- remove documentation for the legacy GPIO API in order to stop
tempting people to use it
- document the preference for using pread() for reading edge events
in the sysfs API
Other:
- add an extended initializer to the interrupt simulator allowing to

irqs being requested and released"

pwm: Changes for v6.11-rc1
This contains the usual mix of fixes, cleanups, two new drivers and several dt binding updates. The fixes are for minor issues that are already old (4.11-rc1 and 3.9-rc1) and were found by code review and not during usage, so I didn't sent them for earlier inclusion. The changes to include/linux/mfd/stm32-timers.h and drivers/counter/stm32-timer-cnt.c are part of an immutable branch that will also be included in the mfd and counter PR. It changes some register definitions and affects the pwm-stm32 driver.

pwm: Add GPIO PWM driver
Add a software PWM which toggles a GPIO from a high-resolution timer. This will naturally not be as accurate or as efficient as a hardware PWM, but it is useful in some cases. I have for example used it for evaluating LED brightness handling (via leds-pwm) on a board where the LED was just hooked up to a GPIO, and for a simple verification of the timer frequency on another platform. Since high-resolution timers are used, sleeping GPIO chips are not supported and are rejected in the probe function.

Documentation: CXL Maturity Map
Provide a survey of the work-in-progress maturity (implementation status) of various aspects of the CXL subsystem. Clarify that in addition to ongoing upkeep relative to specification updates, there are some long running themes in the driver that respond to the discovery of new corner cases (bugs) and new use cases (feature extensions). The primary audience is distribution maintainers, but it also serves as a guide for kernel developers to understand what aspects of the CXL subsystem need more help. It is a landing page to document ongoing progress, and a guide to discern exposure to work-in-progress features.

The usual shower of singleton fixes and minor series all over MM,
documented (hopefully adequately) in the respective changelogs. Notable
series include:
- Lucas Stach has provided some page-mapping
cleanup/consolidation/maintainability work in the series "mm/treewide:
Remove pXd_huge() API".
- In the series "Allow migrate on protnone reference with
MPOL_PREFERRED_MANY policy", Donet Tom has optimized mempolicy's
MPOL_PREFERRED_MANY mode, yielding almost doubled performance in one
test.
- In their series "Memory allocation profiling" Kent Overstreet and
Suren Baghdasaryan have contributed a means of determining (via
/proc/allocinfo) whereabouts in the kernel memory is being allocated:
number of calls and amount of memory.
- Matthew Wilcox has provided the series "Various significant MM
patches" which does a number of rather unrelated things, but in largely
similar code sites.
- In his series "mm: page_alloc: freelist migratetype hygiene" Johannes
Weiner has fixed the page allocator's handling of migratetype requests,
with resulting improvements in compaction efficiency.
- In the series "make the hugetlb migration strategy consistent" Baolin
Wang has fixed a hugetlb migration issue, which should improve hugetlb
allocation reliability.
- Liu Shixin has hit an I/O meltdown caused by readahead in a
memory-tight memcg. Addressed in the series "Fix I/O high when memory
almost met memcg limit".
- In the series "mm/filemap: optimize folio adding and splitting" Kairui
Song has optimized pagecache insertion, yielding ~10% performance
improvement in one test.
- Baoquan He has cleaned up and consolidated the early zone
initialization code in the series "mm/mm_init.c: refactor
free_area_init_core()".

regulator: Updates for v6.10
There's one API update here, a new API factoring out a common pattern for reference voltage supplies. These are supplies uses as a reference by analogue circuits where the consumer requests and enables the supply, reads the voltage to calibrate the user and then never touches it again. This is factored out into a single operation which just returns the voltage and uses devm_ to manage the request and enable portion. Otherwise this has been a very quiet release, we've got some new device support, some small fixes, housekeeping and cleanup work but nothing substantial. There's also some non-regulator changes in here, a number of users for the new reference voltage API were merged along with it and some MFD changes were pulled in as dependencies for new driver work. Highlights: - Add a new API for single operation handling of reference voltages. - Support for Allwinner AXP717 and D1, and NXP PCA9561A. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmZB3mMACgkQJNaLcl1U h9DRmAf9Etp/ydeKGrbYD4K34Ptk4ZwchkTfvPEiNmJEDBlbcazRoeCF9asUVsDR ByggQCahCWhEa+exT+IBQYswpwFRd1oZChSgGUmIS/7pvQDdaPL+53Fnw8SfzmdS QygBEMNN8TGIu2Y+OqEEqINJ407NLbv2SbIlFX1CywZ5hDvCtvFdqhX/xCxTedBN wXlyj2BLe/xmbTGxr3Ssb+l8a0oe1BZvLO6ddrg8DtS92l1zJ0sEk+fegHSQGPRI wI4QehjEgphBsoGhybMGz3ny0nvSs3JkpgRiG/ly3cT97Cx6KSGctMtqjmy7Ynh5 TM3Qq5DS37pBKIm79zmQFbL1z2A9Bw== =wV3x -----END PGP SIGNATURE----- Merge tag 'regulator-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator Pull regulator updates from Mark Brown: "There's one API update here, a new API factoring out a common pattern for reference voltage supplies.

alpha: cleanups and build fixes
I had investigated dropping support for alpha EV5 and earlier a while
ago after noticing that this is the only supported CPU family
in the kernel without native byte access and that Debian has already
dropped support for this generation last year [1] in order to
improve performance for the newer machines.
This topic came up again when Paul E. McKenney noticed that
parts of the RCU code already rely on byte access and do not
work on alpha EV5 reliably, so we decided on using my series to
avoid the problem entirely.
Al Viro did another series for alpha to address all the known build
issues. I rebased his patches without any further changes and included
it as a baseline for my work here to avoid conflicts and allow
backporting the fixes to stable kernels for the now removed hardware
support as well.

Merge tag 'asm-generic-alpha' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic
Pull alpha updates from Arnd Bergmann:
"I had investigated dropping support for alpha EV5 and earlier a while
ago after noticing that this is the only supported CPU family in the
kernel without native byte access and that Debian has already dropped
support for this generation last year [1] in order to improve
performance for the newer machines.
This topic came up again when Paul McKenney noticed that parts of the
RCU code already rely on byte access and do not work on alpha EV5
reliably, so we decided on using my series to avoid the problem
entirely.
Al Viro did another series for alpha to address all the known build
issues. I rebased his patches without any further changes and included
it as a baseline for my work here to avoid conflicts and allow
backporting the fixes to stable kernels for the now removed hardware
support as well"
[ I dearly loved alpha back in the days, but the lack of byte and word
operations was a horrible mistake and made everything worse -
including very much the crazy IO contortions that resulted from it.
It certainly wasn't the only mistake in the architecture, but it's the
first-order issue.
So while it's a bit sad to see the support for my first alpha go away,
if you want to run museum hardware, maybe you should use museum
kernels.. - Linus ]

mm: zswap: remove same_filled module params
These knobs offer more fine-grained control to userspace than needed and
directly expose/influence kernel implementation; remove them.
For disabling same_filled handling, there is no logical reason to refuse
storing same-filled pages more efficiently and opt for compression.
Scanning pages for patterns may be an argument, but the page contents will
be read into the CPU cache anyway during compression. Also, removing the
same_filled handling code does not move the needle significantly in terms
of performance anyway [1].
For disabling non_same_filled handling, it was added when the compressed
pages in zswap were not being properly charged to memcgs, as workloads
could escape the accounting with compression [2]. This is no longer the
case after commit

regulator: devres: add API for reference voltage supplies
A common use case for regulators is to supply a reference voltage to an analog input or output device. This adds a new devres API to get, enable, and get the voltage in a single call. This allows eliminating boilerplate code in drivers that use reference supplies in this way.

fpga: region: add owner module and take its refcount
The current implementation of the fpga region assumes that the low-level
module registers a driver for the parent device and uses its owner pointer
to take the module's refcount. This approach is problematic since it can
lead to a null pointer dereference while attempting to get the region
during programming if the parent device does not have a driver.
To address this problem, add a module owner pointer to the fpga_region
struct and use it to take the module's refcount. Modify the functions for
registering a region to take an additional owner module parameter and
rename them to avoid conflicts. Use the old function names for helper
macros that automatically set the module that registers the region as the
owner. This ensures compatibility with existing low-level control modules
and reduces the chances of registering a region without setting the owner.
Also, update the documentation to keep it consistent with the new interface
for registering an fpga region.

virtio: store owner from modules with register_virtio_driver()
Modules registering driver with register_virtio_driver() might forget to set .owner field. i2c-virtio.c for example has it missing. The field is used by some other kernel parts for reference counting (try_module_get()), so it is expected that drivers will set it. Solve the problem by moving this task away from the drivers to the core virtio code, just like we did for platform_driver in commit |

Currently, the wq_stats output also includes the global stats, while the individual global stats are also available as separate debugfs files. Since these are all read-only, there's really no reason to have them as separate files, especially since we already display them as global stats in the wq_stats.

Pull PCI updates from Bjorn Helgaas:
"Enumeration:
- Consolidate interrupt related code in irq.c (Ilpo Järvinen)
- Reduce kernel size by replacing sysfs resource macros with
functions (Ilpo Järvinen)
- Reduce kernel size by compiling sysfs support only when
CONFIG_SYSFS=y (Lukas Wunner)
- Avoid using Extended Tags on 3ware-9650SE Root Port to work around
an apparent hardware defect (Jörg Wedekind)
Resource management:
- Fix an MMIO mapping leak in pci_iounmap() (Philipp Stanner)
- Move pci_iomap.c and other PCI-specific devres code to drivers/pci
(Philipp Stanner)
- Consolidate PCI devres code in devres.c (Philipp Stanner)
Power management:
- Avoid D3cold on Asus B1400 PCI-NVMe bridge, where firmware doesn't
know how to return correctly to D0, and remove previous quirk that
wasn't as specific (Daniel Drake)
- Allow runtime PM when the driver enables it but doesn't need any
runtime PM callbacks (Raag Jadav)
- Drain runtime-idle callbacks before driver removal to avoid races
between .remove() and .runtime_idle(), which caused intermittent
page faults when the rtsx .runtime_idle() accessed registers that
its .remove() had already unmapped (Rafael J. Wysocki)
Virtualization:
- Avoid Secondary Bus Reset on LSI FW643 so it can be assigned to VMs
with VFIO, e.g., for professional audio software on many Apple
machines, at the cost of leaking state between VMs (Edmund Raile)
Error handling:
- Print all logged TLP Prefixes, not just the first, after AER or DPC
errors (Ilpo Järvinen)

- Collect bits of ASPM-related code that we need even without
CONFIG_PCIEASPM into aspm.c (David E. Box)

separate files for SA8775p, SC7280, SC8180X, SC8280XP, SM8150,
SM8250, SM8350, SM8450, SM8550 for easier reviewing (Krzysztof
Kozlowski)
- Enable BDF to SID translation by disabling bypass mode (Manivannan
Sadhasivam)
- Add endpoint MHI support for Snapdragon SA8775P SoC (Mrinmay
Sarkar)
Synopsys DesignWare PCIe controller driver:

Pull gpio updates from Bartosz Golaszewski:
"The biggest feature is the locking overhaul. Up until now the
synchronization in the GPIO subsystem was broken. There was a single
spinlock "protecting" multiple data structures but doing it wrong (as
evidenced by several places where it would be released when a sleeping
function was called and then reacquired without checking the protected
state).
We tried to use an RW semaphore before but the main issue with GPIO is
that we have drivers implementing the interfaces in both sleeping and
non-sleeping ways as well as user-facing interfaces that can be called
both from process as well as atomic contexts. Both ends converge in
the same code paths that can use neither spinlocks nor mutexes. The
only reasonable way out is to use SRCU and go mostly lockless. To that
end: we add several SRCU structs in relevant places and use them to
assure consistency between API calls together with atomic reads and
writes of GPIO descriptor flags where it makes sense.
This code has spent several weeks in next and has received several
fixes in the first week or two after which it stabilized nicely. The
GPIO subsystem is now resilient to providers being suddenly unbound.
We managed to also remove the existing character device RW semaphore
and the obsolete global spinlock.
Other than the locking rework we have one new driver (for Chromebook
EC), much appreciated documentation improvements from Kent and the
regular driver improvements, DT-bindings updates and GPIOLIB core
tweaks.
Serialization rework:
- use SRCU to serialize access to the global GPIO device list, to
GPIO device structs themselves and to GPIO descriptors

spi: Updates for v6.9
This release sees some exciting changes from David Lechner which
implements some optimisations that have been talked about for a long
time which allows client drivers to pre-prepare SPI messages for
repeated or low latency use. This lets us move work out of latency
sensitive paths and avoid repeating work for frequently performed
operations. As well as being useful in itself this will also be used in
future to allow controllers to directly trigger SPI operations (eg, from
interrupts).
Otherwise this release has mostly been focused on cleanups, plus a
couple of new devices:
- Support for pre-optimising messages.
- A big set of updates from Uwe Kleine-König moving drivers to use APIs
with more modern terminology for controllers.
- Major overhaul of the s3c64xx driver.
- Support for Google GS101 and Samsung Exynos850.

dpll: move all dpll<>netdev helpers to dpll code
Older versions of GCC really want to know the full definition
of the type involved in rcu_assign_pointer().
struct dpll_pin is defined in a local header, net/core can't
reach it. Move all the netdev <> dpll code into dpll, where
the type is known. Otherwise we'd need multiple function calls
to jump between the compilation units.
This is the same problem the commit under fixes was trying to address,
but with rcu_assign_pointer() not rcu_dereference().
Some of the exports are not needed, networking core can't
be a module, we only need exports for the helpers used by
drivers.

USB: document some API requirements on disconnection
A call to usb_set_interface() crashes if the device is deallocated concurrently, such as due to physical removal or a serious IO error. It could also interfere with other drivers using the device if the current driver is unbound before the call is finished. Document the need to delay driver unbinding until this call returns, which solves both issues. Document the same regarding usb_clear_halt(), which is equally known to be routinely called by drivers. Explicitly mention finishing pending operations in the documentation of the driver disconnect callback.

pwm: Provide pwmchip_alloc() function and a devm variant of it
This function allocates a struct pwm_chip and driver data. Compared to the status quo the split into pwm_chip and driver data is new, otherwise it doesn't change anything relevant (yet). The intention is that after all drivers are switched to use this allocation function, its possible to add a struct device to struct pwm_chip to properly track the latter's lifetime without touching all drivers again. Proper lifetime tracking is a necessary precondition to introduce character device support for PWMs (that implements atomic setting and doesn't suffer from the sysfs overhead of the /sys/class/pwm userspace support). The new function pwmchip_priv() (obviously?) only works for chips allocated with pwmchip_alloc().

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Reserve ECAM so we don't assign it to PCI BARs; this works around
bugs where BIOS included ECAM in a PNP0A03 host bridge window,
didn't reserve it via a PNP0C02 motherboard device, and didn't
allocate space for SR-IOV VF BARs (Bjorn Helgaas)
- Add MMCONFIG/ECAM debug logging (Bjorn Helgaas)
- Rename 'MMCONFIG' to 'ECAM' to match spec usage (Bjorn Helgaas)
- Log device type (Root Port, Switch Port, etc) during enumeration
(Bjorn Helgaas)
- Log bridges before downstream devices so the dmesg order is more
logical (Bjorn Helgaas)
- Log resource names (BAR 0, VF BAR 0, bridge window, etc)
consistently instead of a mix of names and "reg 0x10" (Puranjay
Mohan, Bjorn Helgaas)
- Fix 64GT/s effective data rate calculation to use 1b/1b encoding
rather than the 8b/10b or 128b/130b used by lower rates (Ilpo
Järvinen)
- Use PCI_HEADER_TYPE_* instead of literals in x86, powerpc, SCSI
lpfc (Ilpo Järvinen)
- Clean up open-coded PCIBIOS return code mangling (Ilpo Järvinen)
Resource management:
- Restructure pci_dev_for_each_resource() to avoid computing the
address of an out-of-bounds array element (the bounds check was
performed later so the element was never actually *read*, but it's
nicer to avoid even computing an out-of-bounds address) (Andy
Shevchenko)
Driver binding:
- Convert pci-host-common.c platform .remove() callback to
.remove_new() returning 'void' since it's not useful to return
error codes here (Uwe Kleine-König)
- Convert exynos, keystone, kirin from .remove() to .remove_new(),
which returns void instead of int (Uwe Kleine-König)
- Drop unused struct pci_driver.node member (Mathias Krause)
Virtualization:
- Add ACS quirk for more Zhaoxin Root Ports (LeoLiuoc)
Error handling:
- Log AER errors as "Correctable" (not "Corrected") or
"Uncorrectable" to match spec terminology (Bjorn Helgaas)
- Decode Requester ID when no error info found instead of printing
the raw hex value (Bjorn Helgaas)
Endpoint framework:
- Use a unique test pattern for each BAR in the pci_endpoint_test to
make it easier to debug address translation issues (Niklas Cassel)
Broadcom STB PCIe controller driver:
- Add DT property "brcm,clkreq-mode" and driver support for different
CLKREQ# modes to make ASPM L1.x states possible (Jim Quinlan)
Freescale Layerscape PCIe controller driver:
- Add suspend/resume support for Layerscape LS1043a and LS1021a,
including software-managed PME_Turn_Off and transitions between L0,
L2/L3_Ready Link states (Frank Li)
MediaTek PCIe controller driver:
- Clear MSI interrupt status before handler to avoid missing MSIs
that occur after the handler (qizhong cheng)
MediaTek PCIe Gen3 controller driver:
- Update mediatek-gen3 translation window setup to handle MMIO space
that is not a power of two in size (Jianjun Wang)
Qualcomm PCIe controller driver:
- Increase qcom iommu-map maxItems to accommodate SDX55 (five
entries) and SDM845 (sixteen entries) (Krzysztof Kozlowski)
- Describe qcom,pcie-sc8180x clocks and resets accurately (Krzysztof
Kozlowski)
- Describe qcom,pcie-sm8150 clocks and resets accurately (Krzysztof
Kozlowski)
- Correct the qcom "reset-name" property, previously incorrectly
called "reset-names" (Krzysztof Kozlowski)
- Document qcom,pcie-sm8650, based on qcom,pcie-sm8550 (Neil
Armstrong)
Renesas R-Car PCIe controller driver:
- Replace of_device.h with explicit of.h include to untangle header
usage (Rob Herring)
- Add DT and driver support for optional miniPCIe 1.5v and 3.3v
regulators on KingFisher (Wolfram Sang)
SiFive FU740 PCIe controller driver:
- Convert fu740 CONFIG_PCIE_FU740 dependency from SOC_SIFIVE to
ARCH_SIFIVE (Conor Dooley)
Synopsys DesignWare PCIe controller driver:
- Align iATU mapping for endpoint MSI-X (Niklas Cassel)
- Drop "host_" prefix from struct dw_pcie_host_ops members (Yoshihiro
Shimoda)
- Drop "ep_" prefix from struct dw_pcie_ep_ops members (Yoshihiro
Shimoda)
- Rename struct dw_pcie_ep_ops.func_conf_select() to
.get_dbi_offset() to be more descriptive (Yoshihiro Shimoda)
- Add Endpoint DBI accessors to encapsulate offset lookups (Yoshihiro
Shimoda)
TI J721E PCIe driver:
- Add j721e DT and driver support for 'num-lanes' for devices that
support x1, x2, or x4 Links (Matt Ranostay)
- Add j721e DT compatible strings and driver support for j784s4 (Matt
Ranostay)
- Make TI J721E Kconfig depend on ARCH_K3 since the hardware is
specific to those TI SoC parts (Peter Robinson)
TI Keystone PCIe controller driver:
- Hold power management references to all PHYs while enabling them to
avoid a race when one provides clocks to others (Siddharth
Vadapalli)
Xilinx XDMA PCIe controller driver:
- Remove redundant dev_err(), since platform_get_irq() and
platform_get_irq_byname() already log errors (Yang Li)
- Fix uninitialized symbols in xilinx_pl_dma_pcie_setup_irq()
(Krzysztof Wilczyński)
- Fix xilinx_pl_dma_pcie_init_irq_domain() error return when
irq_domain_add_linear() fails (Harshit Mogalapalli)
MicroSemi Switchtec management driver:
- Do dma_mrpc cleanup during switchtec_pci_remove() to match its devm
ioremapping in switchtec_pci_probe(). Previously the cleanup was
done in stdev_release(), which used stale pointers if stdev->cdev
happened to be open when the PCI device was removed (Daniel
Stodden)
Miscellaneous:
- Convert interrupt terminology from "legacy" to "INTx" to be more
specific and match spec terminology (Damien Le Moal)
- In dw-xdata-pcie, pci_endpoint_test, and vmd, replace usage of
deprecated ida_simple_*() API with ida_alloc() and ida_free()
(Christophe JAILLET)"

pwm: Changes for v6.8-rc1
This contains a bunch of cleanups and simplifications across the board, as well as a number of small fixes. Perhaps the most notable change here is the addition of an API that allows PWMs to be used in atomic contexts, which is useful when time- critical operations are involved, such as using a PWM to generate IR signals. Finally, I have decided to step down as PWM subsystem maintainer. Due to other responsibilities I have lately not been able to find the time that the subsystem deserves and Uwe, who has been helping out a lot for the past few years and has many things planned for the future, has kindly volunteered to take over. I have no doubt that he will be a suitable replacement. -----BEGIN PGP SIGNATURE----- iQJNBAABCAA3FiEEiOrDCAFJzPfAjcif3SOs138+s6EFAmWhYQAZHHRoaWVycnku cmVkaW5nQGdtYWlsLmNvbQAKCRDdI6zXfz6zobK8EACtzJX+AeoTkN2S671A7QoG IGl9mrFhvrqN/6syigAIU8ZGOgb5uScZDH58PeTXH/oGEMn+bhQ9MK7JyWF5BUzF I8p6CqaVjG66LsfWz1m8AEAl/0N2Sc2032fWQSJB0o8qgYH0ZRBKc1j371Zm2DgD HT78pZJDSnyCnltPKjbDLShRfBwGINspmbihZKFa6yxrPbvADixCTo19b9Pk8XGa S9k2R/9S/QKPxvB+3DiZAHFstwoTn2p+1IBsg+hp/jLniw8XidZp2Rq0RJuwTjqO jVQDnOFOqNBa3VQccvNe23rDaKUkrmYwk+zzuFF27URam2Gp9wHZ8Y86WPSO5TA9 ftNsoeW++R25PBsOVZFGMU9r9aI9XI1tNyVuv2blNc0yr1fNSRzwjcELzLzG2myp gHgdayJofnvlKM7JV5ZDY6BDPwTP9jfDRdZOqKKNUeB8e9IiQD9JtAV9P+EL/5Hl C+7mh5Xb17bVlczWHqNkTd89Omp+Eu2z5BMfJyiQWQ2lzZpxOkBwB0nrlPshZpPi hz5IhsGjREkEfNV2qz/YDEyaj+CAYO8toitFGt5HeAYTftuG4WD49rHE5VQ8nhwg P9XpWNFHK2EtpU3/BRuupWHZRVd7MU4kMx4WQvWZGOFEqc9DYaC29ynk6sK0ryaC ba8U4gpBS66d3wNvVpkN3A== =pIh8 -----END PGP SIGNATURE----- Merge tag 'pwm/for-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm Pull pwm updates from Thierry Reding: "This contains a bunch of cleanups and simplifications across the board, as well as a number of small fixes.

Another moderately busy cycle for documentation, including:
- The minimum Sphinx requirement has been raised to 2.4.4, following a
warning that was added in 6.2.
- Some reworking of the Documentation/process front page to, hopefully,
make it more useful.
- Various kernel-doc tweaks to, for example, make it deal properly with
__counted_by annotations.
- We have also restored a warning for documentation of nonexistent
structure members that disappeared a while back. That had the delightful
consequence of adding some 600 warnings to the docs build. A sustained
effort by Randy, Vegard, and myself has addressed almost all of those,
bringing the documentation back into sync with the code. The fixes are
going through the appropriate maintainer trees.
- Various improvements to the HTML rendered docs, including automatic links
to Git revisions and a nice new pulldown to make translations easy to
access.
- Speaking of translations, more of those for Spanish and Chinese.
...plus the usual stream of documentation updates and typo fixes.

asm-generic cleanups for 6.8
A series from Baoquan He cleans up the asm-generic/io.h to remove the ioremap_uc() definition from everything except x86, which still needs it for pre-PAT systems. This series notably contains a patch from Jiaxun Yang that converts MIPS to use asm-generic/io.h like every other architecture does, enabling future cleanups. Some of my own patches fix -Wmissing-prototype warnings in architecture specific code across several architectures. This is now needed as the warning is enabled by default. There are still some remaining warnings in minor platforms, but the series should catch most of the widely used ones make them more consistent with one another. David McKay fixes a bug in __generic_cmpxchg_local() when this is used on 64-bit architectures. This could currently only affect parisc64 and sparc64. Additional cleanups address from Linus Walleij, Uwe Kleine-König, Thomas Huth, and Kefeng Wang help reduce unnecessary inconsistencies between architectures. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmWeak8ACgkQYKtH/8kJ UidSiQ/+LL1WTO9d3Zx5HI0GGGjaIYpYs6jUNSf9Y5GPQiOrvjfEWj7CU11/4vxl GlQRpRyncYm8Eiz0Qu+aNxZFiiMah8Uful75yfbX8P1L4EPTbAYNDjkyNJrTjIAK jPK4sl8awIrapOeFUz++PsEj22R/4Is4f0mo+CqoCkL5RKlHe5oFdXzcwjmds4yK CvU6Ldn+M7FZ3EItMdjXaB3D3HS9uictFiO5JByZY8p+IcqgNRI/iHNnZIMsltJ+ XjDi0DG+x4jCj6teElSchw7AofE4OcNSP3xbR1PLKv6+xBLGYaAGZhNuPTz88eV/ Gj0loDQrrR5McGUfDBRHK9zN2Jd0O/FKnfh9kLOt1FLFyGPvC78Q/2HkpVCjbBr2 Pr1aqhLDHA+tGNSsThsV8RUa8/tiEnxAki43tfBFS3SEKhtQsTm2g1z4miwbE3p0 BJIrSgTqrP/SBq7a9z/thPrkzdZcNuA9FUETTbaMeUlJS51n1V9E5A1t7sOG7jaI vV/gbuR6FjvD49mTyQiOSCt3V4ygRqgN1Q+C4QM8WLqq2keUq0AhGodquv8F78in J3x2j2r27lHY7jKf8B0dua/JXAsF20u8qD6yDQ9ymkjt/MWhGXBgK0jpT7RTIuMS e2jmTywUVD4UohAcx3inkOojUhIJ5KDB0I4Pzv4zWcHNbyFNKcY= =4VQl -----END PGP SIGNATURE----- Merge tag 'asm-generic-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pull asm-generic cleanups from Arnd Bergmann: "A series from Baoquan He cleans up the asm-generic/io.h to remove the ioremap_uc() definition from everything except x86, which still needs it for pre-PAT systems.

* MTD
Apart from preventing the mtdblk to run on top of ftl or ubiblk (which
may cause security issues and has no meaning anyway), there are a few
misc fixes.
* Raw NAND
Two meaningful changes this time. The conversion of the brcmnand driver
to the ->exec_op() API, this series brought additional changes to the
core in order to help controller drivers to handle themselves the WP pin
during destructive operations when relevant.
There is also a series bringing important fixes to the sequential read
feature.
As always, there is as well a whole bunch of miscellaneous W=1 fixes,
together with a few runtime fixes (double free, timeout value, OOB
layout, missing register initialization) and the usual load of remove
callbacks turned into void (which led to switch the txx9ndfmc driver to
use module_platform_driver()).
* SPI NOR
SPI NOR comes with die erase support for multi die flashes, with new
octal protocols (1-1-8 and 1-8-8) parsed from SFDP and with an updated
documentation about what the contributors shall consider when proposing
flash additions or updates.
Michael Walle stepped out from the reviewer role to maintainer.

Merge tag 'mtd/for-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux
Pull mtd updates from Miquel Raynal:
"MTD:
- Apart from preventing the mtdblk to run on top of ftl or ubiblk
(which may cause security issues and has no meaning anyway), there
are a few misc fixes.
Raw NAND:
- Two meaningful changes this time. The conversion of the brcmnand
driver to the ->exec_op() API, this series brought additional
changes to the core in order to help controller drivers to handle
themselves the WP pin during destructive operations when relevant.
- There is also a series bringing important fixes to the sequential
read feature.
- As always, there is as well a whole bunch of miscellaneous W=1
fixes, together with a few runtime fixes (double free, timeout
value, OOB layout, missing register initialization) and the usual
load of remove callbacks turned into void (which led to switch the
txx9ndfmc driver to use module_platform_driver()).
SPI NOR:
- SPI NOR comes with die erase support for multi die flashes, with
new octal protocols (1-1-8 and 1-8-8) parsed from SFDP and with an
updated documentation about what the contributors shall consider
when proposing flash additions or updates.
- Michael Walle stepped out from the reviewer role to maintainer"

pwm: Make it possible to apply PWM changes in atomic context
Some PWM devices require sleeping, for example if the pwm device is connected over I2C. However, many PWM devices could be used from atomic context, e.g. memory mapped PWM. This is useful for, for example, the pwm-ir-tx driver which requires precise timing. Sleeping causes havoc with the generated IR signal. Since not all PWM devices can support atomic context, we also add a pwm_might_sleep() function to check if is not supported.

pwm: Rename pwm_apply_state() to pwm_apply_might_sleep()
In order to introduce a pwm api which can be used from atomic context, we will need two functions for applying pwm changes: int pwm_apply_might_sleep(struct pwm *, struct pwm_state *); int pwm_apply_atomic(struct pwm *, struct pwm_state *); This commit just deals with renaming pwm_apply_state(), a following commit will introduce the pwm_apply_atomic() function.

Documentation: Destage TEE subsystem documentation
Add a separate documentation directory for TEE subsystem since it is a standalone subsystem which already offers devices consumed by multiple different subsystem drivers. Split overall TEE subsystem documentation modularly where: - The userspace API has been moved to Documentation/userspace-api/tee.rst. - The driver API has been moved to Documentation/driver-api/tee.rst. - The first module covers the overview of TEE subsystem. - The further modules are dedicated to different TEE implementations like: - OP-TEE - AMD-TEE - and so on for future TEE implementation support.
