Hi!

Based on pdx86/for-next branch. Tested on an Alienware x15 R1.

~ Kurt

v4 -> v5:

[01/14]
  - Remove mention to visibility methods in commit message

[02/14]
  - Register driver during module initialization
  - Make wmi_device_id tables const
  - Add .no_singleton = true to WMI drivers

[04/14]
  - Return -ENOMESG if out_data is true but obj is NULL or not of
    ACPI_TYPE_INTEGER.  

v4: https://lore.kernel.org/platform-driver-x86/20250117081347.8573-1-kuurtb@gmail.com/

Add a state container for the "alienware-wmi" platform device and
initialize it on the new alienfx_probe(). Migrate all LED control functions
to use this state container to support upcoming file split.

Additionally move the led_classdev registration to the platform driver
probe and make it device managed.

Drop alienware_zone_init() and alienware_zone_exit() because they are no
longer needed.

Add WMI drivers for LEGACY and WMAX devices.

This involves moving platform driver and device registration to a helper
function, which is now called from the driver's preferred WMI device
driver probe. However this is only done if !quirks->thermal because
newer WMAX interface doesn't support any of the features exposed by this
device.

Only one driver is registered on module initialization to prevent
registering duplicate platform driver and device.

Additionally, create_thermal_profile() now takes wmi_device * instead of
platform_device *.

Refactor all thermal control methods to use the newly defined awcc_priv
state container instead of global variables. While at it, rename
create_thermal_profile to alienware_awcc_setup and use it to set up the
WMI device "awcc" driver data.

Both WMI devices handled by this module specify a distinct interface for
LED control. Previously this module handled this by dynamically adapting
arguments passed to wmi_evaluate_method() based on the `interface`
global variable.

To avoid the use of global variables, and enable the migration to
non-deprecated WMI methods, let the WMI drivers define upd_led and
upd_brightness operations, which completely replace
alienware_update_led() and wmax_brightness().

Also define alienware_wmi_command(), which serves as a wrapper for
wmidev_evaluate_method(). This new method is very similar to
alienware_wmax_command() but is WMI device agnostic.

use alienware_wmi_command() instead of alienware_wmax_command() which
uses deprecated WMI methods.

Refactor thermal control methods to use alienware_wmi_command() instead
of alienware_wmax_command().

Drop alienware_wmax_command() as there is no more users left.

Split thermal features into a new DMI table to support upcoming file
split. While at it:

Rename quirk_entry -> alienfx_features,
Rename quirks -> alienfx

and change hdmi_mux, amplifier and deepslp types to bool, because they are
already being implicitly used as bools.

Dell has been inactive in its maintainership role of this driver since
around 2021. Due to this, add myself as a maintainer and update path
to support upcoming changes.

Hi Armin,

Thank you so much again for helping me get these series into shape. Your
feedback is very appreciated!

I'm going to rebase this one more time to pick up the fixes branch merge
and this should be ready. 

Also, I already have an HWMON support and manual fan control patchset
ready, that I'll submit once this gets accepted.
