platform/x86: asus-wmi: Fix keyboard brightness cannot be set to 0

2020-01-13T09:50:59+00:00

Some of ASUS laptops like UX431FL keyboard backlight cannot be set to
brightness 0. According to ASUS' information, the brightness should be
0x80 ~ 0x83. This patch fixes it by following the logic.

platform/x86: GPD pocket fan: Allow somewhat lower/higher temperature limits

2020-01-13T09:37:50+00:00

Allow the user to configure the fan to turn on / speed-up at lower
thresholds then before (20 degrees Celcius as minimum instead of 40) and
likewise also allow the user to delay the fan speeding-up till the
temperature hits 90 degrees Celcius (was 70).

platform/x86: GPD pocket fan: Use default values when wrong modparams are given

2020-01-13T09:37:50+00:00

Use our default values when wrong module-parameters are given, instead of
refusing to load. Refusing to load leaves the fan at the BIOS default
setting, which is "Off". The CPU's thermal throttling should protect the
system from damage, but not-loading is really not the best fallback in this
case.

This commit fixes this by re-setting module-parameter values to their
defaults if they are out of range, instead of failing the probe with
-EINVAL.

platform/x86: intel-ips: Use the correct style for SPDX License Identifier

2020-01-13T09:37:50+00:00

This patch corrects the SPDX License Identifier style in
header files related to x86 Platform Specific Drivers.
For C header files Documentation/process/license-rules.rst
mandates C-like comments (opposed to C source files where
C++ style should be used).

GPIO stuff on APUv4 seems to be the same as on APUv2, so we just
need to match on DMI data.

platform/x86: pmc_atom: Add Siemens CONNECT X300 to critclk_systems DMI table

2019-12-20T17:00:50+00:00

The CONNECT X300 uses the PMC clock for on-board components and gets
stuck during boot if the clock is disabled. Therefore, add this
device to the critical systems list.
Tested on CONNECT X300.

platform/x86: hp-wmi: Make buffer for HPWMI_FEATURE2_QUERY 128 bytes

2019-12-20T17:00:50+00:00

At least on the HP Envy x360 15-cp0xxx model the WMI interface
for HPWMI_FEATURE2_QUERY requires an outsize of at least 128 bytes,
otherwise it fails with an error code 5 (HPWMI_RET_INVALID_PARAMETERS):

Dec 06 00:59:38 kernel: hp_wmi: query 0xd returned error 0x5

We do not care about the contents of the buffer, we just want to know
if the HPWMI_FEATURE2_QUERY command is supported.

This commits bumps the buffer size, fixing the error.
