Here are a small number of char/misc/other driver fixes for 5.18-rc5
 
 Nothing major in here, this is mostly IIO driver fixes along with some
 other small things:
 	- at25 driver fix for systems without a dma-able stack
 	- phy driver fixes for reported issues
 	- binder driver fixes for reported issues
 
 All of these have been in linux-next without any reported problems.

c7d2f89fea bus: fsl-mc-msi: Fix MSI descriptor mutex lock for msi_first_desc()
Commit e8604b1447 introduced a call to the helper function
msi_first_desc(), which needs MSI descriptor mutex lock before
call. However, the required mutex lock was not added. This results in
lockdep assertion:

 WARNING: CPU: 4 PID: 119 at kernel/irq/msi.c:274 msi_first_desc+0xd0/0x10c
  msi_first_desc+0xd0/0x10c
  fsl_mc_msi_domain_alloc_irqs+0x7c/0xc0
  fsl_mc_populate_irq_pool+0x80/0x3cc

Fix this by adding the mutex lock and unlock around the function call.

fff8c10368 bus: sunxi-rsb: Fix the return value of sunxi_rsb_device_create()
This code is really spurious.
It always returns an ERR_PTR, even when err is known to be 0 and calls
put_device() after a successful device_register() call.

It is likely that the return statement in the normal path is missing.
Add 'return rdev;' to fix it.

c38f83bae4 bus: mhi: host: pci_generic: Flush recovery worker during freeze
It is possible that the recovery work might be running while the freeze
gets executed (during hibernation etc.,). Currently, we don't powerdown
the stack if it is not up but if the recovery work completes after freeze,
then the device will be up afterwards. This will not be a sane situation.

So let's flush the recovery worker before trying to powerdown the device.

e64d5fa504 bus: mhi: host: pci_generic: Add missing poweroff() PM callback
During hibernation process, once thaw() stage completes, the MHI endpoint
devices will be in M0 state post recovery. After that, the devices will be
powered down so that the system can enter the target sleep state. During
this stage, the PCI core will put the devices in D3hot. But this transition
is allowed by the MHI spec. The devices can only enter D3hot when it is in
M3 state.

So for fixing this issue, let's add the poweroff() callback that will get
executed before putting the system in target sleep state during
hibernation. This callback will power down the device properly so that it
could be restored during restore() or thaw() stage.

a12315d6d2 bus: ti-sysc: Make omap3 gpt12 quirk handling SoC specific
On beagleboard revisions A to B4 we need to use gpt12 as the system timer.
However, the quirk handling added for gpt12 caused a regression for system
suspend for am335x as the PM coprocessor needs the timers idled for
suspend.

Let's make the gpt12 quirk specific to omap34xx, other SoCs don't need
it. Beagleboard revisions C and later no longer need to use the gpt12
related quirk. Then at some point, if we decide to drop support for the old
beagleboard revisions A to B4, we can also drop the gpt12 related quirks
completely.

 updates for 5.18-rc1.
 
 Included in here are merges from driver subsystems which contain:
 	- iio driver updates and new drivers
 	- fsi driver updates
 	- fpga driver updates
 	- habanalabs driver updates and support for new hardware
 	- soundwire driver updates and new drivers
 	- phy driver updates and new drivers
 	- coresight driver updates
 	- icc driver updates
 
 Individual changes include:
 	- mei driver updates
 	- interconnect driver updates
 	- new PECI driver subsystem added
 	- vmci driver updates
 	- lots of tiny misc/char driver updates
 
 There will be two merge conflicts with your tree, one in MAINTAINERS
 which is obvious to fix up, and one in drivers/phy/freescale/Kconfig
 which also should be easy to resolve.
 
 All of these have been in linux-next for a while with no reported
 problems.

ad9c6ee642 spi: Updates for v5.18
The overwhelming bulk of this pull request is a change from Uwe
 Kleine-König which changes the return type of the remove() function to
 void as part of some wider work he's doing to do this for all bus types,
 causing updates to most SPI device drivers.  The branch with that on has
 been cross merged with a couple of other trees which added new SPI
 drivers this cycle, I'm not expecting any build issues resulting from
 the change.
 
 Otherwise it's been a relatively quiet release with some new device
 support, a few minor features and the welcome completion of the
 conversion of the subsystem to use GPIO descriptors rather than numbers:
 
  - Change return type of remove() to void.
  - Completion of the conversion of SPI controller drivers to use GPIO
    descriptors rather than numbers.
  - Quite a few DT schema conversions.
  - Support for multiple SPI devices on a bus in ACPI systems.
  - Big overhaul of the PXA2xx SPI driver.
  - Support for AMD AMDI0062, Intel Raptor Lake, Mediatek MT7986 and
    MT8186, nVidia Tegra210 and Tegra234, Renesas RZ/V2L, Tesla FSD and

Functions like mhi_read_reg_field(), mhi_poll_reg_field() and
mhi_write_reg_field() could be modified to not depend on the shift value
passed as an argument. Instead, the bitfield operation could be used to
extract the shift value from the mask itself.

This eliminates the need to define _SHIFT (and _SHFT) macros and
simplifies the code a bit. For shift values those cannot be determined
during build time, "__ffs()" helper is used find the shift value during
runtime.

While at it, let's also get rid of 32-bit masks like CHDBOFF_CHDBOFF_MASK
by doing the full 32-bit register read.

ed2d980503 bus: mhi: Fix MHI DMA structure endianness
The MHI driver does not work on big endian architectures.  The
controller never transitions into mission mode.  This appears to be due
to the modem device expecting the various contexts and transfer rings to
have fields in little endian order in memory, but the driver constructs
them in native endianness.

Fix MHI event, channel and command contexts and TRE handling macros to
use explicit conversion to little endian.  Mark fields in relevant
structures as little endian to document this requirement.

64f93a9a27 bus: mhi: Fix pm_state conversion to string
On big endian architectures the mhi debugfs files which report pm state
give "Invalid State" for all states.  This is caused by using
find_last_bit which takes an unsigned long* while the state is passed in
as an enum mhi_pm_state which will be of int size.

Fix by using __fls to pass the value of state instead of find_last_bit.

Also the current API expects "mhi_pm_state" enumerator as the function
argument but the function only works with bitmasks. So as Alex suggested,
let's change the argument to u32 to avoid confusion.

4528668ca3 mips: cdmm: Fix refcount leak in mips_cdmm_phys_base
The of_find_compatible_node() function returns a node pointer with
refcount incremented, We should use of_node_put() on it when done
Add the missing of_node_put() to release the refcount.

e6cb540828 bus: imx-weim: add DT overlay support for WEIM bus
Add OF reconfiguration notifier handler for WEIM bus to setup Chip
Select timings on runtime creation of child devices.

However, it is not possible to load another DT overlay with conflicting
CS timings with previously loaded overlay, even if the first one is
unloaded. The reason is that there is no acces to CS timing property of
a device node being removed, thus we can't track which of configured CS
are available for re-configuration.

spi: make remove callback a void function
The value returned by an spi driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

d651ce8e91 bus: mhi: core: Fix race while handling SYS_ERR at power up
During SYS_ERR condition, as a response to the MHI_RESET from host, some
devices tend to issue BHI interrupt without clearing the SYS_ERR state in
the device. This creates a race condition and causes a failure in booting
up the device.

The issue is seen on the Sierra Wireless EM9191 modem during SYS_ERR
handling in mhi_async_power_up(). Once the host detects that the device
is in SYS_ERR state, it issues MHI_RESET and waits for the device to
process the reset request. During this time, the device triggers the BHI
interrupt to the host without clearing SYS_ERR condition. So the host
starts handling the SYS_ERR condition again.

To fix this issue, let's register the IRQ handler only after handling the
SYS_ERR check to avoid getting spurious IRQs from the device.
