Subject: [PATCH 01/19] platform/x86: asus-wmi: Convert all attr-show to use
 sysfs_emit

This changes all *_show attributes in asus-wmi.c to use sysfs_emit()
instead of the older method of writing to the output buffer manually.

Subject: [PATCH 06/19] platform/x86: asus-wmi: Refactor disable_gpu attribute

The settings for these attributes can be read from the device, this
is now done instead of reading a stored value from module. The stored
value is also removed.

This means the simpler asus_wmi_dev_is_present() can be used in
*_check_present() - it is not an error for these methods to be
missing.

The _write() functions have their bodies shifted in to *_store()
which simplifies things further.

Subject: [PATCH 07/19] platform/x86: asus-wmi: Refactor egpu_enable attribute

The settings for these attributes can be read from the device, this
is now done instead of reading a stored value from module. The stored
value is also removed.

This means the simpler asus_wmi_dev_is_present() can be used in
*_check_present() - it is not an error for these methods to be
missing.

The _write() functions have their bodies shifted in to *_store()
which simplifies things further.

Subject: [PATCH 09/19] platform/x86: asus-wmi: Simplify some of the
 *_check_present() helpers

After the recent cleanup patches, some of the *_check_present() helpers
just propagate the result of asus_wmi_dev_is_present().

Replace these with direct asus_wmi_dev_is_present() calls as a further
cleanup.

Subject: [PATCH 10/19] platform/x86: asus-wmi: Support the hardware GPU MUX on
 some laptops

Support the hardware GPU MUX switch available on some models. This
switch can toggle the MUX between:

- 0, Dedicated mode
- 1, Optimus mode

Optimus mode is the regular iGPU + dGPU available, while dedicated
mode switches the system to have only the dGPU available.

Subject: [PATCH 11/19] platform/x86: asus-wmi: Adjust tablet/lidflip handling
 to use enum

Due to multiple types of tablet/lidflip, the existing code for
handling these events is refactored to use an enum for each type.

Subject: [PATCH 13/19] platform/x86: asus-wmi: Simplify tablet-mode-switch
 probing

The 3 different tablet-mode-switch initialization paths repeat a lot
of the same code. Add a helper function for this.

This also makes the error-handling for the kbd_dock_devid case consistent
with the other 2 cases.

Subject: [PATCH 14/19] platform/x86: asus-wmi: Simplify tablet-mode-switch
 handling

Simplify tablet-mode-switch handling:
1. The code is the same for all variants, the only difference is the
   dev_id and notify event code. Store the dev_id + code in struct asus_wmi
   and unify the handling
2. Make the new unified asus_wmi_tablet_mode_get_state() check dev_id has
   been set and make it a no-op when not set. This allows calling it
   unconditionally at resume/restore time
3. Simplify the tablet_mode_sw module-param handling, this also allows
   selecting the new lid-flip-rog type through the module-param.

Subject: [PATCH 17/19] asus-wmi: Implement TUF laptop keyboard LED modes

Adds support for changing the laptop keyboard LED mode and colour.

The modes are visible effects such as static, rainbow, pulsing,
colour cycles.

These sysfs attributes are added to asus::kbd_backlight:
- kbd_rgb_mode
- kbd_rgb_mode_index

Subject: [PATCH 18/19] asus-wmi: Implement TUF laptop keyboard power states

Adds support for setting various power states of TUF keyboards.
These states are combinations of:
- boot, set if a boot animation is shown on keyboard
- awake, set if the keyboard LEDs are visible while laptop is on
- sleep, set if an animation is displayed while the laptop is suspended
- keyboard (unknown effect)

Adds two sysfs attributes to asus::kbd_backlight:
- kbd_rgb_state
- kbd_rgb_state_index

Subject: [PATCH 20/21] asus-wmi: Modify behaviour of Fn+F5 fan key

Some more recent TUF laptops have both fan_boost and thermal_throttle.
The key code for Fn+F5 is also different and unmapped.

This patch adjusts the asus_wmi_handle_event_code() match to match
for both 0x99 and 0xAE, and run both mode switch functions for
fan_boost and/or thermal_throttle if either are available.

It is required that both are tried, as in some instances the ACPI
set-method for one may not have any code body within it even though
it was returned as supported by the get method.

From fe443cc4ff4e12652af1cdae63cff354a2467b67 Mon Sep 17 00:00:00 2001
From: "Luke D. Jones" <luke@ljones.dev>
Date: Fri, 26 Aug 2022 12:34:02 +1200
Subject: [PATCH 21/21] asus-wmi: Support the GPU fan on TUF laptops

Add support for TUF laptops which have the ability to control
the GPU fan. This will show as a second fan in hwmon, and has
the ability to run as boost (fullspeed), or auto.
