45b8ee7182 i2c: mux: gpio: Add support for the 'settle-time-us' property 
Some hardware need some time to switch from a bus to another. This can
cause the first transfers following the selection of a bus to fail.
There is no way to configure this kind of waiting time in the driver.

Add support for the 'settle-time-us' device-tree property. When set,
the i2c_mux_gpio_select() applies a delay before returning, leaving
enough time to the hardware to switch to the new bus.

 ASoC:
 - Large updates throughout the Intel audio drivers
 - Fixes and clarifications for the DAPM documentation
 - Cleanups of accessors for driver data, module labelling, and for
   constification
 - Modernsation and cleanup work in the Mediatek drivers
 - Several fixes and features for the DaVinci I2S driver
 - New drivers for several AMD and Intel platforms, Nuvoton NAU8325,
   Rockchip RK3308 and Texas Instruments PCM6240

The diffstat for this release is dominated by the new Airoha driver,
 mainly as a result of this being a generally quite quiet release.  There
 were a couple of cleanups in the core but nothing substantial, the

  - Overhaul of the PXA2xx driver, mostly API updates.
  - A number of DT binding conversions.
  - Support for Airoha NAND controllers, Cirrus Logic CS35L56, Mobileye

1019fa4839 uio: pruss: Remove this driver 
This UIO driver was used to control the PRU processors found on various
TI SoCs. It was created before the Remoteproc framework, but now with
that we have a standard way to program and manage the PRU processors.
The proper PRU Remoteproc driver should be used instead of this driver.

This driver only supported the original class of PRUSS (OMAP-L1xx /
AM17xx / AM18xx / TMS320C674x / DA8xx) but when these platforms were
switched to use Device Tree the support for DT was not added to this
driver and so it is now unused/unusable. Support for these platforms
can be added to the proper PRU Remoteproc driver if ever needed.

Remove this driver.

ASoC: ti: davinci-i2s: Remove the unused clk_input_pin attribute 
The clk_input_pin attribute of davinci_mcbsp_dev struct is not set since
commit 257ade78b6 ("ASoC: davinci-i2s: Convert to use edma-pcm").

Remove the attribute.
Keep the behaviour of the MCBSP_CLKR case as MCBSP_CLKR == 0.
I can't test the BC_FP format so I added back the initial comment that
was removed by commit ec63755337 ("ASoC: DaVinci: Added selection of
clk input pin for McBSP"). This was the last dependency to
linux/platform_data/davinci_asp.h so it is not included anymore.

Remove the enum mcbsp_clk_input_pin from davinci_asp.h as it is not used
anywhere else.

The implementation is not respectful of the actual spi_message
content, so the CS can be raised after each word even if the
transfer structure asks to keep the CS active for the whole operation.

As it is not used anyway in the current Linux tree, it can be safely
removed.

The include/linux/platform_data/x86/pmc_atom.h d3_sts register bit defines
are named after how these bits are used on Bay Trail devices.

On Cherry Trail (CHT) devices some of these bits have a different meaning
according to the datasheet.

At a comment to the defines for bits which have a different meaning

clk: x86: Move clk-pmc-atom register defines to include/linux/platform_data/x86/pmc_atom.h 
Move the register defines for the Atom (Bay Trail, Cherry Trail) PMC
clocks to include/linux/platform_data/x86/pmc_atom.h.

This is a preparation patch to extend the S0i3 readiness checks
in drivers/platform/x86/pmc_atom.c with checking that the PMC
clocks are off on suspend entry.

Note these are added to include/linux/platform_data/x86/pmc_atom.h rather
then to include/linux/platform_data/x86/clk-pmc-atom.h because the former
already has all the other Atom PMC register defines.

ee975351cf net: mdio: mdio-bcm-unimac: Manage clock around I/O accesses 
Up until now we have managed not to have the mdio-bcm-unimac manage its
clock except during probe and suspend/resume. This works most of the
time, except where it does not.

With a fully modular build, we can get into a situation whereby the
GENET driver is fully registered, and so is the mdio-bcm-unimac driver,
however the Ethernet PHY driver is not yet, because it depends on a
resource that is not yet available (e.g.: GPIO provider). In that state,
the network device is not usable yet, and so to conserve power, the
GENET driver will have turned off its "main" clock which feeds its MDIO
controller.

When the PHY driver finally probes however, we make an access to the PHY
registers to e.g.: disable interrupts, and this causes a bus error
within the MDIO controller space because the MDIO controller clock(s)
are turned off.

To remedy that, we manage the clock around all of the I/O accesses to
the hardware which are done exclusively during read, write and clock
divider configuration.

This ensures that the register space is accessible, and this also
ensures that there are not unnecessarily elevated reference counts
keeping the clocks active when the network device is administratively
turned off. It would be the case with the previous way of managing the
clock.

05013062a8 pwm: lpss-*: Make use of devm_pwmchip_alloc() function 
This prepares the pwm-lpss drivers to further changes of the pwm core
outlined in the commit introducing devm_pwmchip_alloc(). There is no
intended semantical change and the driver should behave as before.

2719a9e715 wifi: cw1200: Convert to GPIO descriptors 
The CW1200 uses two GPIOs to control the powerup and reset
pins, get these from GPIO descriptors instead of being passed
as platform data from boardfiles.

The RESET line will need to be marked as active low as we will
let gpiolib handle the polarity inversion.

The SDIO case is a bit special since the "card" need to be
powered up before it gets detected on the SDIO bus and
properly probed. Fix this by using board-specific GPIOs
assigned to device "NULL".

There are currently no in-tree users.

 CLASS_SPD support gets simplified to prepare removal in the future.

 Furthermore, I2C core now creates a debugfs directory per I2C adapter.

3e7aeb78ab Networking changes for 6.8. 
Core & protocols
 ----------------
 
  - Analyze and reorganize core networking structs (socks, netdev,
    netns, mibs) to optimize cacheline consumption and set up
    build time warnings to safeguard against future header changes.
    This improves TCP performances with many concurrent connections
    up to 40%.
 
  - Add page-pool netlink-based introspection, exposing the
    memory usage and recycling stats. This helps indentify
    bad PP users and possible leaks.
 
  - Refine TCP/DCCP source port selection to no longer favor even
    source port at connect() time when IP_LOCAL_PORT_RANGE is set.
    This lowers the time taken by connect() for hosts having
    many active connections to the same destination.
 
  - Refactor the TCP bind conflict code, shrinking related socket
    structs.
 
  - Refactor TCP SYN-Cookie handling, as a preparation step to
    allow arbitrary SYN-Cookie processing via eBPF.
 
  - Tune optmem_max for 0-copy usage, increasing the default value
    to 128KB and namespecifying it.
 
  - Allow coalescing for cloned skbs coming from page pools, improving
    RX performances with some common configurations.
 
  - Reduce extension header parsing overhead at GRO time.
 
  - Add bridge MDB bulk deletion support, allowing user-space to
    request the deletion of matching entries.
 
  - Reorder nftables struct members, to keep data accessed by the
    datapath first.
 
  - Introduce TC block ports tracking and use. This allows supporting
    multicast-like behavior at the TC layer.
 
  - Remove UAPI support for retired TC qdiscs (dsmark, CBQ and ATM) and
    classifiers (RSVP and tcindex).
 
  - More data-race annotations.
 
  - Extend the diag interface to dump TCP bound-only sockets.
 
  - Conditional notification of events for TC qdisc class and actions.
 
  - Support for WPAN dynamic associations with nearby devices, to form
    a sub-network using a specific PAN ID.
 
  - Implement SMCv2.1 virtual ISM device support.
 
  - Add support for Batman-avd mulicast packet type.
 
 BPF
 ---
 
  - Tons of verifier improvements:
    - BPF register bounds logic and range support along with a large
      test suite
    - log improvements
    - complete precision tracking support for register spills
    - track aligned STACK_ZERO cases as imprecise spilled registers. It
      improves the verifier "instructions processed" metric from single
      digit to 50-60% for some programs
    - support for user's global BPF subprogram arguments with few
      commonly requested annotations for a better developer experience
    - support tracking of BPF_JNE which helps cases when the compiler
      transforms (unsigned) "a > 0" into "if a == 0 goto xxx" and the
      like
    - several fixes
 
  - Add initial TX metadata implementation for AF_XDP with support in
    mlx5 and stmmac drivers. Two types of offloads are supported right
    now, that is, TX timestamp and TX checksum offload.
 
  - Fix kCFI bugs in BPF all forms of indirect calls from BPF into
    kernel and from kernel into BPF work with CFI enabled. This allows
    BPF to work with CONFIG_FINEIBT=y.
 
  - Change BPF verifier logic to validate global subprograms lazily
    instead of unconditionally before the main program, so they can be
    guarded using BPF CO-RE techniques.
 
  - Support uid/gid options when mounting bpffs.
 
  - Add a new kfunc which acquires the associated cgroup of a task
    within a specific cgroup v1 hierarchy where the latter is identified
    by its id.
 
  - Extend verifier to allow bpf_refcount_acquire() of a map value field
    obtained via direct load which is a use-case needed in sched_ext.
 
  - Add BPF link_info support for uprobe multi link along with bpftool
    integration for the latter.
 
  - Support for VLAN tag in XDP hints.
 
  - Remove deprecated bpfilter kernel leftovers given the project
    is developed in user-space (https://github.com/facebook/bpfilter).
 
 Misc
 ----
 
  - Support for parellel TC self-tests execution.
 
  - Increase MPTCP self-tests coverage.
 
  - Updated the bridge documentation, including several so-far
    undocumented features.
 
  - Convert all the net self-tests to run in unique netns, to
    avoid random failures due to conflict and allow concurrent
    runs.

Merge tag 'net-next-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Paolo Abeni:
 "The most interesting thing is probably the networking structs
  reorganization and a significant amount of changes is around
  self-tests.

  Core & protocols:

   - Analyze and reorganize core networking structs (socks, netdev,
     netns, mibs) to optimize cacheline consumption and set up build
     time warnings to safeguard against future header changes

     This improves TCP performances with many concurrent connections up
     to 40%

   - Add page-pool netlink-based introspection, exposing the memory
     usage and recycling stats. This helps indentify bad PP users and
     possible leaks

   - Refine TCP/DCCP source port selection to no longer favor even
     source port at connect() time when IP_LOCAL_PORT_RANGE is set. This
     lowers the time taken by connect() for hosts having many active
     connections to the same destination

   - Refactor the TCP bind conflict code, shrinking related socket
     structs

   - Refactor TCP SYN-Cookie handling, as a preparation step to allow
     arbitrary SYN-Cookie processing via eBPF

   - Tune optmem_max for 0-copy usage, increasing the default value to
     128KB and namespecifying it

   - Allow coalescing for cloned skbs coming from page pools, improving
     RX performances with some common configurations

   - Reduce extension header parsing overhead at GRO time

   - Add bridge MDB bulk deletion support, allowing user-space to
     request the deletion of matching entries

   - Reorder nftables struct members, to keep data accessed by the
     datapath first

   - Introduce TC block ports tracking and use. This allows supporting
     multicast-like behavior at the TC layer

   - Remove UAPI support for retired TC qdiscs (dsmark, CBQ and ATM) and
     classifiers (RSVP and tcindex)

   - More data-race annotations

   - Extend the diag interface to dump TCP bound-only sockets

   - Conditional notification of events for TC qdisc class and actions

   - Support for WPAN dynamic associations with nearby devices, to form
     a sub-network using a specific PAN ID

   - Implement SMCv2.1 virtual ISM device support

   - Add support for Batman-avd mulicast packet type

  BPF:

   - Tons of verifier improvements:
       - BPF register bounds logic and range support along with a large
         test suite
       - log improvements
       - complete precision tracking support for register spills
       - track aligned STACK_ZERO cases as imprecise spilled registers.
         This improves the verifier "instructions processed" metric from
         single digit to 50-60% for some programs
       - support for user's global BPF subprogram arguments with few
         commonly requested annotations for a better developer
         experience
       - support tracking of BPF_JNE which helps cases when the compiler
         transforms (unsigned) "a > 0" into "if a == 0 goto xxx" and the
         like
       - several fixes

   - Add initial TX metadata implementation for AF_XDP with support in
     mlx5 and stmmac drivers. Two types of offloads are supported right
     now, that is, TX timestamp and TX checksum offload

   - Fix kCFI bugs in BPF all forms of indirect calls from BPF into
     kernel and from kernel into BPF work with CFI enabled. This allows
     BPF to work with CONFIG_FINEIBT=y

   - Change BPF verifier logic to validate global subprograms lazily
     instead of unconditionally before the main program, so they can be
     guarded using BPF CO-RE techniques

   - Support uid/gid options when mounting bpffs

   - Add a new kfunc which acquires the associated cgroup of a task
     within a specific cgroup v1 hierarchy where the latter is
     identified by its id

   - Extend verifier to allow bpf_refcount_acquire() of a map value
     field obtained via direct load which is a use-case needed in
     sched_ext

   - Add BPF link_info support for uprobe multi link along with bpftool
     integration for the latter

   - Support for VLAN tag in XDP hints

   - Remove deprecated bpfilter kernel leftovers given the project is
     developed in user-space (https://github.com/facebook/bpfilter)

  Misc:

   - Support for parellel TC self-tests execution

   - Increase MPTCP self-tests coverage

   - Updated the bridge documentation, including several so-far
     undocumented features

   - Convert all the net self-tests to run in unique netns, to avoid
     random failures due to conflict and allow concurrent runs

   - Add TCP-AO self-tests

   - Add kunit tests for both cfg80211 and mac80211

   - Autogenerate Netlink families documentation from YAML spec

   - Add yml-gen support for fixed headers and recursive nests, the tool
     can now generate user-space code for all genetlink families for
     which we have specs

Alvin Šipraga
b2adbc9cea clk: si5351: allow PLLs to be adjusted without reset 
Introduce a new PLL reset mode flag which controls whether or not to
reset a PLL after adjusting its rate. The mode can be configured through
platform data or device tree.

Since commit 6dc669a22c ("clk: si5351: Add PLL soft reset"), the
driver unconditionally resets a PLL whenever its rate is adjusted.
The rationale was that a PLL reset was required to get three outputs
working at the same time. Before this change, the driver never reset the
PLLs.

Commit b26ff127c5 ("clk: si5351: Apply PLL soft reset before enabling
the outputs") subsequently introduced an option to reset the PLL when
enabling a clock output that sourced it. Here, the rationale was that
this is required to get a deterministic phase relationship between
multiple output clocks.

This clearly shows that it is useful to reset the PLLs in applications
where multiple clock outputs are used. However, the Si5351 also allows
for glitch-free rate adjustment of its PLLs if one avoids resetting the
PLL. In our audio application where a single Si5351 clock output is used
to supply a runtime adjustable bit clock, this unconditional PLL reset
behaviour introduces unwanted glitches in the clock output.

It would appear that the problem being solved in the former commit
may be solved by using the optional device tree property introduced in
the latter commit, obviating the need for an unconditional PLL reset
after rate adjustment. But it's not OK to break the default behaviour of
the driver, and it cannot be assumed that all device trees are using the
property introduced in the latter commit. Hence, the new behaviour is
made opt-in.

e53c18da99 Input: omap-keypad - drop optional GPIO support 
The driver supports passing some GPIO lines for rows and columns
through the driver data, but there is no in-kernel user of this.

Further the use seems convoluted because the GPIO lines are unused
in the driver, then explicitly free:ed when removing it without
being requested when probing it, which is assymetric and just
a recepie for disaster.

Remove the support for these unused GPIOs, if need be support can
be reestablished in an organized fashion using GPIO descriptors.
