Pull x86 platform driver updates from Andy Shevchenko:
"Gathered a bunch of x86 platform driver changes. It's rather big,
since includes two big refactors and completely new driver:
- ASUS WMI driver got a big refactoring in order to support the TUF
Gaming laptops. Besides that, the regression with backlight being
permanently off on various EeePC laptops has been fixed.
- Accelerometer on HP ProBook 450 G0 shows wrong measurements due to
X axis being inverted. This has been fixed.
- Intel PMC core driver has been extended to be ACPI enumerated if
the DSDT provides device with _HID "INT33A1". This allows to
convert the driver to be pure platform and support new hardware
purely based on ACPI DSDT.
- From now on the Intel Speed Select Technology is supported thru a
corresponding driver. This driver provides an access to the
features of the ISST, such as Performance Profile, Core Power, Base
frequency and Turbo Frequency.
- Mellanox platform drivers has been refactored and now extended to
support more systems, including new coming ones.
- The OLPC XO-1.75 platform is now supported.
- CB4063 Beckhoff Automation board is using PMC clocks, provided via
pmc_atom driver, for ethernet controllers in a way that they can't
be managed by the clock driver. The quirk has been extended to
cover this case.
- Touchscreen on Chuwi Hi10 Plus tablet has been enabled. Meanwhile
the information of Chuwi Hi10 Air has been fixed to cover more
models based on the same platform.
- Xiaomi notebooks have WMI interface enabled. Thus, the driver to
support it has been provided. It required some extension of the
generic WMI library, which allows to propagate opaque context to
the ->probe() of the individual drivers.
This release includes debugfs clean up from Greg KH for several
drivers that drop return code check and make debugfs absence or
failure non-fatal.
Also miscellaneous fixes here and there, mostly for Acer WMI and
various Intel drivers"

Description: These files allow asserting system power cycling, switching

power supply units on and off and system's main power domain

shutdown.
|
|
Expected behavior:
|
|
When pwr_cycle is written 1: auxiliary power domain will go
|
|
down and after short period (about 1 second) up.
|
|
When psu1_on or psu2_on is written 1, related unit will be
|
|
disconnected from the power source, when written 0 - connected.
|
|
If both are written 1 - power supplies main power domain will
|
|
go down.
|
|
When pwr_down is written 1, system's main power domain will go
|
|
down.
