Here is the char/misc/iio and other smaller driver subsystem updates for
7.1-rc1. Lots of stuff in here, all tiny, but relevant for the
different drivers they touch. Major points in here is:
- the usual large set of new IIO drivers and updates for that
subsystem (the large majority of this diffstat)
- lots of comedi driver updates and bugfixes
- coresight driver updates
- interconnect driver updates and additions
- mei driver updates
- binder (both rust and C versions) updates and fixes
- lots of other smaller driver subsystem updates and additions
All of these have been in linux-next for a while with no reported
issues.

- sysfs support for tee firmware information
- minor updates to platform specific TEE drivers for AMD, NXP, Qualcomm
and the generic optee driver
- ARM SCMI firmware refactoring to improve the protocol discover
among other fixes and cleanups
- ARM FF-A firmware interoperability improvements
The reset controller and memory controller subsystems gain support for
additional hardware platforms from Mediatek, Renesas, NXP, Canaan and
SpacemiT.
Most of the other changes are for random drivers/soc code. Among
a number of cleanups and newly added hardware support, including:

Some devices reserve a larger NVMEM region for the U-Boot environment
than the actual environment data length used by U-Boot itself. The CRC32
in the U-Boot header is calculated over the smaller data length, causing
CRC validation to fail when Linux reads the full partition.
Allow an optional device tree property "env-size" to specify the
environment data size to use for CRC computation.

DTS example in the bindings should be indented with 2- or 4-spaces and
aligned with opening '- |', so correct any differences like 3-spaces or
mixtures 2- and 4-spaces in one binding.
No functional changes here, but saves some comments during reviews of
new patches built on existing code.

On MT8186 and MT8188 one of the NVMEM cells contains the GPU speed bin
value. In combination with the GPU OPP bindings, on these two platforms
there is an implied scheme of converting the cell value to what the GPU
OPP "opp-supported-hw" property matches. This does not apply to the base
mediatek,efuse hardware, nor does it apply to any of the other platforms
that do not have the GPU speed bin cell. The platform maintainer argues
that this makes the compatibles incompatible with the base
"mediatek,efuse" compatible, as shown in the link given.
Deprecate the MT8186/MT8188 + "mediatek,efuse" combination, and add
new entries with MT8186 being the base model and MT8188 falling back
to MT8186.

NVMEM nodes can optionally include the bits property to specify the bit
position of the cell within a byte.
Extend patternProperties to allow adding the bit offset to the node
address to be able to distinguish nodes with the same address but
different bit positions, e.g.
trim@54,4 {
reg = <0x54 1>;
bits = <4 2>;
};
trim@54,0 {
reg = <0x54 1>;
bits = <0 4>;
};
Before the conversion to NVMEM layouts in commit bd912c991d
("dt-bindings: nvmem: layouts: add fixed-layout") this extension was
originally added with commit 4b2545dd19 ("dt-bindings: nvmem: Extend
patternProperties to optionally indicate bit position") to the now
deprecated layout.

Here is the big char/misc/iio and other small driver subsystem pull
request for 6.16-rc1.
Overall, a lot of individual changes, but nothing major, just the normal
constant forward progress of new device support and cleanups to existing
subsystems. Highlights in here are:
- Large IIO driver updates and additions and device tree changes
- Android binder bugfixes and logfile fixes
- mhi driver updates
- comedi driver updates
- counter driver updates and additions
- coresight driver updates and additions
- echo driver removal as there are no in-kernel users of it
- nvmem driver updates
- spmi driver updates
- new amd-sbi driver "subsystem" and drivers added
- rust miscdriver binding documentation fix
- other small driver fixes and updates (uio, w1, acrn, hpet, xillybus,
cardreader drivers, fastrpc and others.)
All of these have been in linux-next for quite a while with no reported

GPIO core:
- use more lock guards where applicable
- refactor GPIO ACPI code and shrink it in the process by 8%
- move GPIO ACPI quirks into a separate file
- remove unneeded #ifdef
- convert GPIO devres helpers to using devm_add_action() where applicable
which shrinks and simplifies the code
- refactor GPIO descriptor validation in GPIO consumer interfaces
- don't allow setting values on input lines in the GPIO core which will
take off the burden from GPIO drivers of checking this down the line
- provide gpiod_is_equal() as a way of safely comparing two GPIO
descriptors (the only current user is in regulator core)
New drivers:
- add the GPIO module for the max77759 multifunction device
- add the GPIO driver for the VeriSilicon BLZP1600 GPIO controller
- add the GPIO driver for the Spacemit K1 SoC
Driver improvements:
- convert more drivers to using the new GPIO line value setter callbacks
- convert more drivers to making the irq_chip immutable as is recommended
by the interrupt subsystem
- extend build testing coverage by enabling more modules to be built with
COMPILE_TEST=y
- extend the gpio-aggregator module with a configfs interface that makes
the setup easier for user-space than the existing driver-level sysfs
attributes and also adds more advanced configuration features (such as
referring to aggregated lines by their original names or modifying
their names as exposed by the aggregated chip)
- add a missing mutex_destroy() in gpio-imx-scu
- add an OF polarity quirk for s5m8767
- allow building gpio-vf610 as a loadable module
- make gpio-mxc not hardcode its GPIO base number with GPIO SYSFS
interface disabled (another small step towards getting rid of the global
GPIO numberspace)
- add support for level-triggered interrupts to gpio-pca953x
- don't double-check the ngpios property in gpio-ds4520 as GPIO core
already does it

If NVMEM uses a data stride bigger than a byte, the starting bit of the
cell might be bigger than a byte (e.g. if the data comes in the second
byte of the 4-byte word). Allow the staring bit to be 8 or greater to
reflect such usecases.

properly. Should make many SteamOS users happy. Even comes with
