2021-09-14platform/x86: wmi: remove unnecessary checksBarnabás Pőcze
The `find_guid_context()` is only called from one place, and `wblock` and `wdriver` cannot be NULL there. So remove the currently redundant checks.

2021-09-14platform/x86: amd-pmc: Increase the response register timeoutMario Limonciello
There have been reports of approximately a 0.9%-1.7% failure rate in SMU communication timeouts with s0i3 entry on some OEM designs. Currently the design in amd-pmc is to try every 100us for up to 20ms. However the GPU driver which also communicates with the SMU using a mailbox register which the driver polls every 1us for up to 2000ms. In the GPU driver this was increased by commit 055162645a40 ("drm/amd/pm: increase time out value when sending msg to SMU") Increase the maximum timeout used by amd-pmc to 2000ms to match this behavior. This has been shown to improve the stability for machines that randomly have failures.

2021-09-14platform/x86: Add driver for ACPI WMAA EC-based backlight controlDaniel Dadap
A number of upcoming notebook computer designs drive the internal display panel's backlight PWM through the Embedded Controller (EC). This EC-based backlight control can be plumbed through to an ACPI "WMAA" method interface, which in turn can be wrapped by WMI with the GUID handle 603E9613-EF25-4338-A3D0-C46177516DB7. Add a new driver, aliased to the WMAA WMI GUID, to expose a sysfs backlight class driver to control backlight levels on systems with EC-driven backlights.

2021-09-14platform/x86: hp-wmi: add support for omen laptopsEnver Balalic
This patch adds support for HP Omen laptops. It adds support for most things that can be controlled via the Windows Omen Command Center application. - Fan speed monitoring through hwmon - Platform Profile support (cool, balanced, performance) - Max fan speed function toggle Also exposes the existing HDD temperature through hwmon since this driver didn't use hwmon before this patch. This patch has been tested on a 2020 HP Omen 15 (AMD) 15-en0023dx. - V1 Initial Patch - V2 Use standard hwmon ABI attributes Add existing non-standard "hddtemp" to hwmon - V3 Fix overflow issue in "hp_wmi_get_fan_speed" Map max fan speed value back to hwmon values on read Code style fixes Fix issue with returning values from "hp_wmi_hwmon_read", the value to return should be written to val and not just returned from the function - V4 Use DMI Board names to detect if a device should use the omen specific thermal profile method. Select HWMON instead of depending on it. Code style fixes. Replace some error codes with more specific/meaningful ones. Remove the HDD temperature from HWMON since we don't know what unit it's expressed in. Handle error from hp_wmi_hwmon_init - V5 Handle possible NULL from dmi_get_system_info() Use match_string function instead of manually checking Directly use is_omen_thermal_profile() without the static variable.

Alder PCH uses the same Gigabit Ethernet (GBE) device as Tiger Lake PCH which cannot achieve PC10 without ignoring the PMC GBE LTR. Add this work around for Alder Lake PCH as well.

2021-08-20platform/x86/intel: pmc/core: Add Alder Lake low power mode support for pmc coreGayatri Kammela
Alder Lake has 14 status registers that are memory mapped. These registers show the status of the low power mode requirements. The registers are latched on every C10 entry or exit and on every s0ix.y entry/exit. Accessing these registers is useful for debugging any low power related activities. Thus, add debugfs entry to access low power mode status registers.
