of: Create of_root if no dtb provided by firmware
When enabling CONFIG_OF on a platform where 'of_root' is not populated by firmware, we end up without a root node. In order to apply overlays and create subnodes of the root node, we need one. Create this root node by unflattening an empty builtin dtb. If firmware provides a flattened device tree (FDT) then the FDT is unflattened via setup_arch(). Otherwise, the call to unflatten(_and_copy)?_device_tree() will create an empty root node. We make of_have_populated_dt() return true only if the DTB was loaded by firmware so that existing callers don't change behavior after this patch. The call in the of platform code is removed because it prevents overlays from creating platform devices when the empty root node is used.

of/platform: Inform about created platform devices using pr_debug()
For most nodes with a compatible property a platform device is created. For some an amba device is created instead. For the latter of_amba_device_create() emits a message at debug level about the node the device is created from. Add a similar message to of_platform_device_create_pdata() to inform about the whole list of created devices. This also gives the right context for the following messages that inform about created child devices.

of: device: Export of_device_make_bus_id()
This helper is really handy to create unique device names based on their device tree path, we may need it outside of the OF core (in the NVMEM subsystem) so let's export it. As this helper has nothing patform specific, let's move it to of/device.c instead of of/platform.c so we can add its prototype to of_device.h.

of/platform: Disable sysfb if a simple-framebuffer node is found
Some DT platforms use EFI to boot and in this case the EFI Boot Services
may register a EFI_GRAPHICS_OUTPUT_PROTOCOL handle, that will later be
queried by the Linux EFI stub to fill the global struct screen_info data.
The data is used by the Generic System Framebuffers (sysfb) framework to
add a platform device with platform data about the system framebuffer.
But if there is a "simple-framebuffer" node in the DT, the OF core will
also do the same and add another device for the system framebuffer.
This could lead for example, to two platform devices ("simple-framebuffer"
and "efi-framebuffer") to be added and matched with their corresponding
drivers. So both efifb and simpledrm will be probed, leading to following:
[ 0.055752] efifb: framebuffer at 0xbd58dc000, using 16000k, total 16000k
[ 0.055755] efifb: mode is 2560x1600x32, linelength=10240, pages=1
[ 0.055758] efifb: scrolling: redraw
[ 0.055759] efifb: Truecolor: size=2:10:10:10, shift=30:20:10:0
...
[ 3.295896] simple-framebuffer bd58dc000.framebuffer: [drm] *ERROR*
could not acquire memory range [??? 0xffff79f30a29ee40-0x2a5000001a7
flags 0x0]: -16
[ 3.298018] simple-framebuffer: probe of bd58dc000.framebuffer
failed with error -16
To prevent the issue, make the OF core to disable sysfb if there is a node
with a "simple-framebuffer" compatible. That way only this device will be
registered and sysfb would not attempt to register another one using the
screen_info data even if this has been filled.
This seems the correct thing to do in this case because:
a) On a DT platform, the DTB is the single source of truth since is what
describes the hardware topology. Even if EFI Boot Services are used to
boot the machine.
b) The of_platform_default_populate_init() function is called in the
arch_initcall_sync() initcall level while the sysfb_init() function
is called later in the subsys_initcall() initcall level.

amba: bus: balance firmware node reference counting
Currently the ACPI code doesn't bump the reference count of the firmware node, while OF counter part does. Not that it's a problem right now, since ACPI doesn't really use the reference counting for firmware nodes, it still makes sense to make code robust against any changes done there. For this, - switch ACPI case to use device_set_node() to be unified with OF - move reference counting to amba_device_add() - switch to use firmware nodes instead of OF ones In the result we will have reference counting done in the same module for all callers independently on the nature of firmware node behind.

treewide: Fix probing of devices in DT overlays
When loading a DT overlay that creates a device, the device is not
probed, unless the DT overlay is unloaded and reloaded again.
After the recent refactoring to improve fw_devlink, it no longer depends
on the "compatible" property to identify which device tree nodes will
become struct devices. fw_devlink now picks up dangling consumers
(consumers pointing to descendent device tree nodes of a device that
aren't converted to child devices) when a device is successfully bound
to a driver. See __fw_devlink_pickup_dangling_consumers().
However, during DT overlay, a device's device tree node can have
sub-nodes added/removed without unbinding/rebinding the driver. This
difference in behavior between the normal device instantiation and
probing flow vs. the DT overlay flow has a bunch of implications that
are pointed out elsewhere[1]. One of them is that the fw_devlink logic
to pick up dangling consumers is never exercised.
This patch solves the fw_devlink issue by marking all DT nodes added by
DT overlays with FWNODE_FLAG_NOT_DEVICE (fwnode that won't become
device), and by clearing the flag when a struct device is actually
created for the DT node. This way, fw_devlink knows not to have
consumers waiting on these newly added DT nodes, and to propagate the
dependency to an ancestor DT node that has the corresponding struct
device.
Based on a patch by Saravana Kannan, which covered only platform and spi
devices.

of: Create platform devices for OF framebuffers
Create a platform device for each OF-declared framebuffer and have offb bind to these devices. Allows for real hot-unplugging and other drivers besides offb. Originally, offb created framebuffer devices while initializing its module by parsing the OF device tree. No actual Linux device was set up. This tied OF framebuffers to offb and makes writing other drivers for the OF framebuffers complicated. The absence of a Linux device further prevented real hot-unplugging. Adding a distinct platform device for each OF framebuffer solves both problems. Specifically, a DRM driver can now provide graphics output for modern userspace. Some of the offb init code is now located in the OF initialization. There's now also an implementation of of_platform_default_populate_init(), which was missing before. The OF side creates different devices for either OF display nodes or BootX displays as they require different handling by the driver. The offb drivers picks up each type of device and runs the appropriate fbdev initialization. Tested with OF display nodes on qemu's ppc64le target. v3: * declare variable 'node' with function scope (Rob) v2: * run PPC code as part of existing initialization (Rob) * add a few more error warnings (Javier) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Reviewed-by: Rob Herring <robh@kernel.org> Link: https://patchwork.freedesktop.org/patch/msgid/20220419100405.12600-2-tzimmermann@suse.de |

of/platform: Drop static setup of IRQ resource from DT core
Now that all the DT drivers have switched to platform_get_irq() we can now safely drop the static setup of IRQ resource from DT core code. With the above change hierarchical setup of irq domains is no longer bypassed and thus allowing hierarchical interrupt domains to describe interrupts using "interrupts" DT property.

misc: open-dice: Add driver to expose DICE data to userspace
Open Profile for DICE is an open protocol for measured boot compatible with the Trusted Computing Group's Device Identifier Composition Engine (DICE) specification. The generated Compound Device Identifier (CDI) certificates represent the hardware/software combination measured by DICE, and can be used for remote attestation and sealing. Add a driver that exposes reserved memory regions populated by firmware with DICE CDIs and exposes them to userspace via a character device. Userspace obtains the memory region's size from read() and calls mmap() to create a mapping of the memory region in its address space. The mapping is not allowed to be write+shared, giving userspace a guarantee that the data were not overwritten by another process. Userspace can also call write(), which triggers a wipe of the DICE data by the driver. Because both the kernel and userspace mappings use write-combine semantics, all clients observe the memory as zeroed after the syscall has returned.

ARM: SoC drivers for 5.16
These are all the driver updates for SoC specific drivers. There
are a couple of subsystems with individual maintainers picking up
their patches here:
- The reset controller subsystem add support for a few new SoC
variants to existing drivers, along with other minor improvements
- The OP-TEE subsystem gets a driver for the ARM FF-A transport
- The memory controller subsystem has improvements for Tegra,
Mediatek, Renesas, Freescale and Broadcom specific drivers.
- The tegra cpuidle driver changes get merged through this
tree this time. There are only minor changes, but they depend
on other tegra driver updates here.
- The ep93xx platform finally moves to using the drivers/clk/
subsystem, moving the code out of arch/arm in the process.
This depends on a small sound driver change that is included
here as well.
- There are some minor updates for Qualcomm and Tegra specific
firmware drivers.
The other driver updates are mainly for drivers/soc, which contains
a mixture of vendor specific drivers that don't really fit elsewhere:
- Mediatek drivers gain more support for MT8192, with new support for
hw-mutex and mmsys routing, plus support for reset lines in the
mmsys driver.
- Qualcomm gains a new "sleep stats" driver, and support for
the "Generic Packet Router" in the APR driver.
- There is a new user interface for routing the UARTS on ASpeed
BMCs, something that apparently nobody else has needed so far.
- More drivers can now be built as loadable modules, in particular
for Broadcom and Samsung platforms.
- Lots of improvements to the TI sysc driver for better suspend/resume
support
Finally, there are lots of minor cleanups and new device IDs for
amlogic, renesas, tegra, qualcomm, mediateka, samsung, imx, layerscape,
allwinner, broadcom, and omap.

The other driver updates are mainly for drivers/soc, which contains a
mixture of vendor specific drivers that don't really fit elsewhere:
- Mediatek drivers gain more support for MT8192, with new support for
hw-mutex and mmsys routing, plus support for reset lines in the
mmsys driver.
- Qualcomm gains a new "sleep stats" driver, and support for the
"Generic Packet Router" in the APR driver.
- There is a new user interface for routing the UARTS on ASpeed BMCs,
something that apparently nobody else has needed so far.
- More drivers can now be built as loadable modules, in particular
for Broadcom and Samsung platforms.
- Lots of improvements to the TI sysc driver for better
suspend/resume support"
Finally, there are lots of minor cleanups and new device IDs for
amlogic, renesas, tegra, qualcomm, mediateka, samsung, imx,
layerscape, allwinner, broadcom, and omap"

ARM: 9119/1: amba: Properly handle device probe without IRQ domain
of_amba_device_create() uses irq_of_parse_and_map() to translate a DT interrupt specification into a Linux virtual interrupt number. But it doesn't properly handle the case where the interrupt controller is not yet available, eg, when pl011 interrupt is connected to MBIGEN interrupt controller, because the mbigen initialization is too late, which will lead to no IRQ due to no IRQ domain found, log is shown below, "irq: no irq domain found for uart0 !" use of_irq_get() to return -EPROBE_DEFER as above, and in the function amba_device_try_add()/amba_device_add(), it will properly handle in such case, also return 0 in other fail cases to be consistent as before.

soc: qcom: smem: Support reserved-memory description
Practically all modern Qualcomm platforms has a single reserved-memory region for SMEM. So rather than having to describe SMEM in the form of a node with a reference to a reserved-memory node, allow the SMEM device to be instantiated directly from the reserved-memory node. The current means of falling back to dereferencing the "memory-region" is kept as a fallback, if it's determined that the SMEM node is a reserved-memory node. The "qcom,smem" compatible is added to the reserved_mem_matches list, to allow the reserved-memory device to be probed. In order to retain the readability of the code, the resolution of resources is split from the actual ioremapping.

Char/Misc driver patches for 5.12-rc1
Here is the large set of char/misc/whatever driver subsystem updates for
5.12-rc1. Over time it seems like this tree is collecting more and more
tiny driver subsystems in one place, making it easier for those
maintainers, which is why this is getting larger.
Included in here are:
- coresight driver updates
- habannalabs driver updates
- virtual acrn driver addition (proper acks from the x86
maintainers)
- broadcom misc driver addition
- speakup driver updates
- soundwire driver updates
- fpga driver updates
- amba driver updates
- mei driver updates
- vfio driver updates
- greybus driver updates
- nvmeem driver updates
- phy driver updates
- mhi driver updates
- interconnect driver udpates
- fsl-mc bus driver updates
- random driver fix
- some small misc driver updates (rtsx, pvpanic, etc.)
All of these have been in linux-next for a while, with the only reported
issue being a merge conflict in include/linux/mod_devicetable.h that you
will hit in your tree due to the dfl_device_id addition from the fpga
subsystem in here. The resolution should be simple.

nvmem: Add driver to expose reserved memory as nvmem
Firmware/co-processors might use reserved memory areas in order to pass data stemming from an nvmem device otherwise non accessible to Linux. For example an EEPROM memory only physically accessible to firmware, or data only accessible early at boot time. In order to expose this data to other drivers and user-space, the driver models the reserved memory area as an nvmem device.

of: platform: Destroy child devices symmetrically
Iterate over child devices in reverse when unpopulating a platform device to make this step symmetrical with the population step. This fixes an issue in the Tegra DRM driver where upon module unload the DPAUX controller tries to unregister an I2C controller but will end up waiting indefinitely because one of the SOR devices is keeping a reference to it. Since the SOR devices are instantiated after the DPAUX devices, they would only be removed (and hence release their reference to the I2C controller) after the DPAUX devices have been removed. While destroying the child devices in reverse order helps in this situation, it isn't fully safe to do so either. An even better way would be for the child devices to be reordered to match the probe order, which would work irrespective of the instantiation order. However, reordering by probe order would be fairly complicated and doesn't fix any known issues, so we'll go with the simpler fix for now.

of/platform: Pause/resume sync state during init and of_platform_populate()
When all the top level devices are populated from DT during kernel init, the supplier devices could be added and probed before the consumer devices are added and linked to the suppliers. To avoid the sync_state() callback from being called prematurely, pause the sync_state() callbacks before populating the devices and resume them at late_initcall_sync(). Similarly, when children devices are populated from a module using of_platform_populate(), there could be supplier-consumer dependencies between the children devices that are populated. To avoid the same problem with sync_state() being called prematurely, pause and resume sync_state() callbacks across of_platform_populate().

Driver Core and debugfs changes for 5.3-rc1
Here is the "big" driver core and debugfs changes for 5.3-rc1
It's a lot of different patches, all across the tree due to some api
changes and lots of debugfs cleanups. Because of this, there is going
to be some merge issues with your tree at the moment, I'll follow up
with the expected resolutions to make it easier for you.
Other than the debugfs cleanups, in this set of changes we have:
- bus iteration function cleanups (will cause build warnings
with s390 and coresight drivers in your tree)
- scripts/get_abi.pl tool to display and parse Documentation/ABI
entries in a simple way
- cleanups to Documenatation/ABI/ entries to make them parse
easier due to typos and other minor things
- default_attrs use for some ktype users
- driver model documentation file conversions to .rst
- compressed firmware file loading
- deferred probe fixes
All of these have been in linux-next for a while, with a bunch of merge
issues that Stephen has been patient with me for. Other than the merge
issues, functionality is working properly in linux-next :)

If that qualifier is also used in the bus_find_device() prototype, it will be possible to pass the same match() callback function to both bus_find_device() and class_find_device(), which will allow some optimizations to be made in order to avoid code duplication going forward. Also with that, constify the "data" parameter as it is passed as a const to the match function. For this reason, change the prototype of bus_find_device() to match the prototype of class_find_device() and adjust its callers to use the const qualifier in accordance with the new prototype of it.

Devicetree updates for 4.20:
- Sync dtc with upstream version v1.4.7-14-gc86da84d30e4
- Work to get rid of direct accesses to struct device_node name and
type pointers in preparation for removing them. New helpers for
parsing DT cpu nodes and conversions to use the helpers. printk
conversions to %pOFn for printing DT node names. Most went thru
subystem trees, so this is the remainder.
- Fixes to DT child node lookups to actually be restricted to child
nodes instead of treewide.
- Refactoring of dtb targets out of arch code. This makes the support
more uniform and enables building all dtbs on c6x, microblaze, and
powerpc.
- Various DT binding updates for Renesas r8a7744 SoC
- Vendor prefixes for Facebook, OLPC
- Restructuring of some ARM binding docs moving some peripheral bindings
out of board/SoC binding files
- New "secure-chosen" binding for secure world settings on ARM
- Dual licensing of 2 DT IRQ binding headers

Pull Devicetree updates from Rob Herring:
"A bit bigger than normal as I've been busy this cycle.
There's a few things with dependencies and a few things subsystem
maintainers didn't pick up, so I'm taking them thru my tree.
The fixes from Johan didn't get into linux-next, but they've been
waiting for some time now and they are what's left of what subsystem
maintainers didn't pick up.
