e6a70a02de wireless-drivers-next patches for v5.15
First set of patches for v5.15. This got delayed as I have been mostly
 offline for the last few weeks. The biggest change is removal of
 prism54 driver, otherwise just smaller changes.
 
 Major changes:
 
 ath5k, ath9k, ath10k, ath11k:
 
 * switch from 'pci_' to 'dma_' API
 
 brcmfmac
 
 * allow per-board firmware binaries
 
 * add support 43752 SDIO device
 
 prism54
 
 * remove the obsoleted driver, everyone should be using p54 driver instead

cd92dbaf5d MAINTAINERS: adjust PISTACHIO SOC SUPPORT after its retirement
Commit 104f942b2832 ("MIPS: Retire MACH_PISTACHIO") removes
./arch/mips/pistachio/ and ./arch/mips/configs/pistachio_defconfig, but
misses to adjust the corresponding section PISTACHIO SOC SUPPORT
in MAINTAINERS.

Hence, ./scripts/get_maintainer.pl --self-test=patterns complains:

  warning: no file matches    F:    arch/mips/configs/pistachio*_defconfig
  warning: no file matches    F:    arch/mips/pistachio/

As James Hartley is not reachable with the provided email address, the
remaining dtsi file, arch/mips/boot/dts/img/pistachio.dtsi, must be
maintained by its only user pistachio_marduk.dts, which is part of MARDUK
(CREATOR CI40) DEVICE TREE SUPPORT.

Add maintenance of pistachio.dtsi to that section and drop the PISTACHIO
SOC SUPPORT after its retirement.

structure has one member. It will be expanded later to handle this
difference.

dcfbd31ef4 platform/x86: BIOS SAR driver for Intel M.2 Modem
Dynamic BIOS SAR driver exposing dynamic SAR information from BIOS

The Dynamic SAR (Specific Absorption Rate) driver uses ACPI DSM
(Device Specific Method) to communicate with BIOS and retrieve
dynamic SAR information and change notifications. The driver uses
sysfs to expose this data to userspace via read and notify.

Sysfs interface is documented in detail under:
Documentation/ABI/testing/sysfs-driver-intc_sar

f805ef1ce5 First set of new IIO and counter device support, cleanups and features for 5.15
Usual mix of cleanups and new device support.
 
 Counter
 ======
 
 Cleanups and refactoring:
 * treewide
   - Ensure attempts to set invalid modes result in -EINVAL return.
   - Rename counter_count_function to counter_function as the middle count
     is redundant.
   - Standardize error returns when limits are exceeded.
 * 104-quad:
   - Document the lock.
   - Return an error if attempt to set the ceiling value in a mode that
     doesn't support it.
 * intel-qep
   - Drop unused bitops.h include
 
 IIO
 ===
 
 New device support
 * bma255
   - Add support fo the bosch,bmc156_accel which oddly only exposes the INT2
     interrupt pin and not INT1. Patch set includes enabling use of INT2.
 * ingenic_adc
   - Add support for JZ4760 and similar and update bindings
   - Add support for JZ4760B and update bindings
 * rockchip_saradc
   - Add support for rk3568 ADC (separate channel array as more channels)
 * sgp40 gas sensor used to measure air quality
   - New driver including binding and ABI documentation.
 
 Bindings
 --------
 
 * Add missing bindings for many DACs where the binding was effectively
   implicit due to fallback probe methods in I2C and SPI.

 * bosch,bma255
   - Interrupt type in example was opposite of what the device expects.
     It's possible that a particular board had an inverter, but we
     definitely don't want the example to suggest this would be normal.
   - Add interrupt-names to allow for cases where only INT2 is connected.
   - Sort compatibles
   - Merge in very similar bosch,bma180 binding.
 
 New feature
 -----------
 
 * Devices only allowed to provide either extended_name or a label for given
   channel. If extend_name is used (generally discouraged but can't be
   removed as it would be a userspaece ABI change), then the label sysfs
   attribute will provide the extended_name. This allows some userspace
   parser simplications and hardening.
 * hid-sensors-pres
   - Add a timestamp channel (either from hardware, or locally filled).
 * vcnl3020
   - Add periodic sensor mode used to provide IIO events.
 
 Cleanups / minor fixes
 ----------------------
 
 * core/buffers
   - Avoid unnecessary zeroing of bitmaps that are immediately overwritten.
   - Move a sanity check earlier to simplify error path.
 * Quite a few cases of refactors to use devm_* for all of probe and drop
   remove
   - adjd_s311

   - da280

   - ds311
   - max5481
   - max5821
   - rfd77402
   - tcs3414
   - tmp006
 * ad5624r
   - Fix incorrect handling of a regulator that was preventing use of
     internal regulators.
 * adjd_s311
   - Allocate a buffer as part of iio_priv() structure as maximum size
     is small enough, no significant advantage in making it flexible sized.
 * bma220
   - Make handling of suspend and resume closer to the probe() wrt to the
     rather odd interface, that suspend mode is entered by reading a register.
 * ep93xx
   - Prepare clock before using (part of conversion to CCF)
 * fsl-imx25-gcq
   - Use local device pointer.
   - Adjust handling of platform_get_irq() to not check for 0 as an error.
     The function is documented as never returning it.
 * hid-sensors
   - Use devm_kmemdup() consistently across all drivers to simplify channel
     structure allocation management.
 * meson-saradc
   - Drop BL30 integration on G12A and newer SoCs as not used.
   - Whitespace fixes.
 * mpu6050
   - Add per device type startup times. This avoids an issue with having
     to dsicard initial data from gyroscopes when they were still stabilizing.
 * rfd77402
   - Change from passing private data, to passing i2c_client where only
     that is needed, reducing back and forth in pm functions.
 * si1145
   - Drop pointless continue
 * st-sensors
   - Cleanup of includes to remove unused and add missing headers that are used.

e4637f6212 MAINTAINERS: Remove the ipx network layer info
commit <47595e32869f> ("<MAINTAINERS: Mark some staging directories>")
indicated the ipx network layer as obsolete in Jan 2018,
updated in the MAINTAINERS file.

now, after being exposed for 3 years to refactoring, so to
remove the ipx network layer info from MAINTAINERS.
additionally, there is no module that depends on ipx.h
except a broken staging driver(r8188eu)

1bb24be00c SCMI Updates for v5.15
The bulk of the addition this time is mainly refactoring to add support
 for Virtio transport for SCMI and the addition of the support itself.
 The refactoring includes allowing transport specific init/exit calls,
 making each transport as compile time configurable, supporting
 monotonically increasing tokens instead of using the next available
 free buffer index as the token for scmi messages which eases handling
 concurrent and out-of-order messages which is a must have for virtio
 transport.
 
 Virtio support itself is conformant to the virtio SCMI device spec [1].
 Virtio device id 32 has been reserved for the SCMI device [2].
 
 Other than the virtio support, there is one bug fix in the probe failure
 clean up path.
