Subject: [PATCH 02/29] platform/x86: asus-wmi: don't fail if platform_profile
already registered
On some newer laptops it appears that an AMD driver can register a
platform_profile handler. If this happens then the asus_wmi driver would
error with -EEXIST when trying to register its own handler leaving the
user with a possibly unusable system - this is especially true for
laptops with an MCU that emit a stream of HID packets, some of which can
be misinterpreted as shutdown signals.
We can safely continue loading the driver instead of bombing out.

Subject: [PATCH 03/29] acpi/x86: s2idle: add support for screen off and screen
on callbacks
All the _DSM methods for the LPS0 method are called back to back
currently. The intended use of the screen off and screen on calls is
supposed to be matching the screen being turned on or off though.
Add support for other parts of the kernel to call such a callback.

Subject: [PATCH 06/29] platform/x86: asus-wmi: Refactor Ally suspend/resume
The CSEE method from ACPI is now called only on module load. This fixes
an issues with USB device loss on Ally 1 after reboot.
Both Ally 1 and Ally X now rely only of the _DSM screen off/on calls
exposed in AMD s2idle to call the CSEE (which is done in the _DSM), plus
a small additional delay to allow the MCU time to do USB unplug/plug.
Note: a new MCU FW is being released on 2024/10/16 which will completely
fix the issue this quirk series has been trying to fix, and it will be
able to be removed in full some time in the future. This quirk series
has also been tested with a test version of this FW fix with no ill
effects - users will notice only that powersave becomes reliable 100% of
the time.

Subject: [PATCH 08/29] hid-asus: Add MODULE_IMPORT_NS(ASUS_WMI)
A small change to asus_wmi_evaluate_method() was introduced during
asus-armoury driver development to put the exports behind a namespace.
Import that namespace here.

Subject: [PATCH 09/29] platform/x86: asus-armoury: move existing tunings to
asus-armoury module
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The fw_attributes_class provides a much cleaner interface to all of the
attributes introduced to asus-wmi. This patch moves all of these extra
attributes over to fw_attributes_class, and shifts the bulk of these
definitions to a new kernel module to reduce the clutter of asus-wmi
with the intention of deprecating the asus-wmi attributes in future.
The work applies only to WMI methods which don't have a clearly defined
place within the sysfs and as a result ended up lumped together in
/sys/devices/platform/asus-nb-wmi/ with no standard API.
Where possible the fw attrs now implement defaults, min, max, scalar,
choices, etc. As en example dgpu_disable becomes:
/sys/class/firmware-attributes/asus-armoury/attributes/dgpu_disable/
├── current_value
├── display_name
├── possible_values
└── type
as do other attributes.
The ppt_* based attributes are removed in this initial patch as the
implementation is somewhat broken due to the WMI methods requiring a
set of limits on the values accepted (which is not provided by WMI).

Subject: [PATCH 15/29] platform/x86: asus-wmi: deprecate bios features
With the existence of the asus-armoury module the attributes no-longer
need to live under the /sys/devices/platform/asus-nb-wmi/ path.
Deprecate all those that were implemented in asus-bioscfg with the goal
of removing them fully in the next LTS cycle.

Subject: [PATCH 16/29] ALSA: hda/realtek: fixup ASUS GA605W
The GA605W laptop has almost the exact same codec setup as the GA403
and so the same quirks apply to it.
