the diff is all the new Qualcomm clk drivers added for a few SoCs they're
working on. The other two vendors with significant work this cycle are Renesas
and Amlogic. Renesas adds a bunch of clks to existing drivers and supports some
new SoCs while Amlogic is starting a significant refactoring to simplify their
code.
The core framework gained a pair of helpers to get the 'struct device' or
'struct device_node' associated with a 'struct clk_hw'. Some associated KUnit
tests were added for these simple helpers as well. Beyond that core change
there are lots of little fixes throughout the clk drivers for the stuff we see
every day, wrong clk driver data that affects tree topology or supported
frequencies, etc. They're not found until the clks are actually used by some
consumer device driver.
New Drivers:
- Global, display, gpu, video, camera, tcsr, and rpmh clock controller for the
Qualcomm Milos SoC
- Camera, display, GPU, and video clock controllers for Qualcomm QCS615
- Video clock controller driver for Qualcomm SM6350

Add support for the Texas Instruments INA228 Ultra-Precise
Power/Energy/Charge Monitor.
The INA228 is very similar to the INA238 but offers four bits of extra
precision in the temperature, voltage and current measurement fields.
It also supports energy and charge monitoring, the latter of which is
not supported through this patch.
While it seems in the datasheet that some constants such as LSB values
differ between the 228 and the 238, they differ only for those registers
where four bits of precision have been added and they differ by a factor
of 16 (VBUS, VSHUNT, DIETEMP, CURRENT).
Therefore, the INA238 constants are still applicable with regard
to the bit of the same significance.

Add support for using the AMC6821 as a cooling device. The AMC6821
registers with the thermal framework only if the `cooling-levels`
property is present in the fan device tree child node. If this property
is present, the driver assumes the fan will operate in open-loop, and
the kernel will control it directly. In this case, the driver will
change the AMC6821 mode to manual (software DCY) and set the initial PWM
duty cycle to the maximum fan cooling state level as defined in the DT.
It is worth mentioning that the cooling device is registered on the
child fan node, not on the fan controller node. Existing behavior is
unchanged, so the AMC6821 can still be used without the thermal
framework (hwmon only).

The Linux hwmon sysfs API values for pwmX_auto_pointY_pwm represent an

represent millidegrees Celcius.
Commit a6d80df47e ("hwmon: (gsc-hwmon) fix fan pwm temperature
scaling") properly addressed the incorrect scaling in the
pwm_auto_point_temp_store implementation but erroneously scaled
the pwm_auto_point_pwm_show (pwm value) instead of the
pwm_auto_point_temp_show (temp value) resulting in:
# cat /sys/class/hwmon/hwmon0/pwm1_auto_point6_pwm
25500
# cat /sys/class/hwmon/hwmon0/pwm1_auto_point6_temp
4500
Fix the scaling of these attributes:
# cat /sys/class/hwmon/hwmon0/pwm1_auto_point6_pwm
255
# cat /sys/class/hwmon/hwmon0/pwm1_auto_point6_temp

The GPIO output functionality does not work as intended.
The ucd9000_gpio_set function should set UCD9000_GPIO_CONFIG_OUT_VALUE
(bit 2) in order to change the output value of the selected GPIO.
Instead UCD9000_GPIO_CONFIG_STATUS (bit 3) is set, but this is a
read-only value. This patch fixes the mistake and provides the intended
functionality of the GPIOs.
See UCD90xxx Sequencer and System Health Controller PMBus Command SLVU352C
section 10.43 for reference.

The hwmon sysfs interface specifies that energy values should be
reported in microjoules. This is also what tools such as lmsensors
expect, reporting wrong values otherwise.
Adjust the driver to scale the output accordingly and adjust ina238
driver documentation.

The adi-axi-common.h header has some common defines used in various ADI
IPs. However they are not specific for any fpga manager so it's
questionable for the header to live under include/linux/fpga. Hence
let's just move one directory up and update all users.

clang produces an output with excessive stack usage when building the
occ_setup_sensor_attrs() function, apparently the result of having
a lot of struct literals and building with the -fno-strict-overflow
option that leads clang to skip some optimization in case the 'attr'
pointer overruns:
drivers/hwmon/occ/common.c:775:12: error: stack frame size (1392) exceeds limit (1280) in 'occ_setup_sensor_attrs' [-Werror,-Wframe-larger-than]
Replace the custom macros for initializing the attributes with a
simpler function call that does not run into this corner case.

In the fts_read() function, when handling hwmon_pwm_auto_channels_temp,
the code accesses the shared variable data->fan_source[channel] twice
without holding any locks. It is first checked against
FTS_FAN_SOURCE_INVALID, and if the check passes, it is read again
when used as an argument to the BIT() macro.
This creates a Time-of-Check to Time-of-Use (TOCTOU) race condition.
Another thread executing fts_update_device() can modify the value of
data->fan_source[channel] between the check and its use. If the value
is changed to FTS_FAN_SOURCE_INVALID (0xff) during this window, the
BIT() macro will be called with a large shift value (BIT(255)).
A bit shift by a value greater than or equal to the type width is
undefined behavior and can lead to a crash or incorrect values being
returned to userspace.
Fix this by reading data->fan_source[channel] into a local variable
once, eliminating the race condition. Additionally, add a bounds check
to ensure the value is less than BITS_PER_LONG before passing it to
the BIT() macro, making the code more robust against undefined behavior.
This possible bug was found by an experimental static analysis tool
developed by our team.

- 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

According to the ISL28022 datasheet, bit15 of the current register is
representing -32768. Fix the calculation to properly handle this bit,
ensuring correct measurements for negative values.

Use the I3C private transfer input buffer pointer for incoming data
instead of output buffer. For now this is harmless since both of those
pointers are union members but may confuse when reading the code.

The KEBA fan controller is found in the system FPGA of KEBA PLC devices.
It detects if the fan is removed or blocked. For fans with tacho signal
the monitoring of the speed of the fan is supported. It also supports to
regulate the speed of fans with PWM input.
The auxiliary device for this driver is instantiated by the cp500 misc
driver.

Add support for the Monolithic Power Systems MPM3695 family.
It contains four devices with suffixes: -10, -20, -25 and -100.
The device is PMBus compliant and shares characteristics with the
MPM82504.
MPM3695-25 has different VOLTAGE_SCALE_LOOP register size [11:0]
and therefore needs to have a separate compatible entry.
Tested with device tree based matching (MPM3695-10).

Implement support for setting the VOUT_SCALE_LOOP PMBus register
based on an optional device tree property
"mps,vout-fb-divider-ratio-permille".
This allows the driver to provide the correct VOUT value depending
on the feedback voltage divider configuration for chips where the
bootloader does not configure the VOUT_SCALE_LOOP register.
