Pull pwm updates from Uwe Kleine-König:
"Apart from the usual mix of new drivers (pwm-argon-fan-hat), adding
support for variants to existing drivers, minor improvements to both
drivers and docs, device tree documenation updates, the noteworthy
changes are:
- A hwmon companion driver to pwm-mc33xs2410 living in drivers/hwmon
and acked by Guenter Roeck
- chardev support for PWM devices. This leverages atomic PWM updates
to userspace and at the same time simplifies and accelerates PWM

Introduce hardware monitoring support for the following devices:

ADP1055: 6 PWM for I/O Voltage, I/O Current, Power, Temperature
LTP8800-1A/-2/-4A: 150A/135A/200A DC/DC µModule Regulator
The ADP1051 and ADP1055 are similar digital controllers for high
efficiency DC-DC power conversion while the LTP8800 is a family of
step-down μModule regulators that provides microprocessor core voltage
from 54V power distribution architecture. All of the above components
features telemetry monitoring of input/output voltage, input current,
output power, and temperature over PMBus.

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

The EC of OneXPlayer devices used to only control the fan. This is no
longer the case, with the EC of OneXPlayer gaining additional
functionality (turbo button, turbo led, battery controls).
As it will be beneficial from a complexity perspective to retain this
driver as a single unit, move it out of hwmon, and into platform/x86.
Also, remove the hwmon documentation to prepare moving it to
Documentation/ABI/.
While at it, add myself to the maintainer's file.

Add initial support for the Texas Instruments TPS25990 eFuse.
This adds the basic PMBUS telemetry support for the device.
From Karol Przybylski:
The tps25990_read_word_data function contains a block of unreachable code
caused by the syntactic structure in the PMBUS_VIRT_READ_IIN_MAX case.
Specifically, the return TPS25990_READ_IIN_PEAK; statement immediately
exits the function, making the next lines unreachable.
This patch removes the return statement, leaving the expected handling.

Writing PMBus protected registers does succeed from the smbus perspective,
even if the write is ignored by the device and a communication fault is
raised. This fault will silently be caught and cleared by pmbus irq if one
has been registered.
This means that the regulator call may return succeed although the
operation was ignored.
With this change, the operation which are not supported will be properly
flagged as such and the regulator framework won't even try to execute them.
