The device is able to monitor temperature, voltage and current of each of
the four outputs. Add basic support for monitoring the temperature of the
four outputs and the die temperature.

Pull char / misc / iio driver updates from Greg KH:
"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 problems"

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 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.

INA260 is similar to other chips of the series, except it has an internal
shunt resistor. The calibration register is therefore not present. Also,
the current register address was changed, though that does not matter for
the driver since the shunt voltage register (which is now the current
register) value is already used to read the current.

The embedded controller code is mainly used on x86 laptops and cannot
work without PC style I/O port access.
Make this a user-visible configuration option that is default enabled
on x86 but otherwise disabled, and that can never be enabled unless
CONFIG_HAS_IOPORT is also available.
The empty stubs in internal.h help ignore the EC code in configurations
that don't support it. In order to see those stubs, the sbshc code also
has to include this header and drop duplicate declarations.
All the direct callers of ec_read/ec_write already had an x86
dependency and now also need to depend on APCI_EC.

Some of the newer Microsoft Surface devices (such as the Surface Book
3 and Pro 9) have thermal sensors connected via the Surface Aggregator
Module (the embedded controller on those devices). Add a basic driver
to read out the temperature values of those sensors.
The EC can have up to 16 thermal sensors connected via a single
sub-device, each providing temperature readings and a label string.

Use regmap for register accesses and caching.
While at it, use sysfs_emit() instead of sprintf() to write sysfs
attribute data, and remove spurious debug messages which would only
be seen as result of a bug in the code. Also make sure that error
codes are propagated and not replaced with -EIO.
While at it, introduce rounding of written temperature values and for
internal calculations to reduce deviation from written values and as
much as possible.
No functional change intended except for differences introduced by
rounding.

With SPD5118 chip detection for the most part handled by the i2c-smbus
core using DMI information, the spd5118 driver no longer needs to
auto-detect spd5118 compliant chips.
Auto-detection by the driver is still needed on systems with no DMI support
or on systems with more than eight DIMMs and can not be removed entirely.
However, it affects boot time and introduces the risk of mis-identifying
chips. Add configuration option to be able to disable it on systems where
chip detection is handled outside the driver.

The driver support two functions: PWM and Tachometer. The PWM feature can
handle up to 16 output ports, while the Tachometer can monitor to up to 16
input ports as well. This driver implements them by exposing two kernel
subsystems: PWM and HWMON. The PWM subsystem can be utilized alongside
existing drivers for controlling elements such as fans (pwm-fan.c),
beepers (pwm-beeper.c) and so on. Through the HWMON subsystem, the driver
provides sysfs interfaces for fan.
