[PATCH v3 00/20] platform/x86: alienware-wmi driver rework

[Kurt Borja]

Hello :) 

I rebased this series on top of review-ilpo-next to pick up
alienware-wmi's latest commit.

v2 -> v3:

[5/20]
 - Use traditional if statement in zone_attr_visible and return attr->mode

[7/20]
 - Remove quirks from priv

[8/20]
 - Call alienware_alienfx_exit if device_add_groups fails
 - Call device_remove_groups on .remove
 - Return ret on alienware_wmi_init()

[9/20]
 - Directly return create_thermal_profile in alienware_awcc_setup()
 - Assign priv on declaration in alienware_awcc_exit()

[10/20]
 - Fix alienware_wmi_command()

[13/20]
 - Rename x_series_features -> generic_quirks
 - Rename g_series_features -> g_series_quirks
 - Keep previous module parameter logic
 - Additionally rename *quirks -> *alienfx

[16/20]
 - Export *alienfx as an extern variable on alienware-wmi.h
 - Move pr_fmt to alienware-wmi.h

[17/20]
 - 2024 -> 2025

[20/20]
 - 2024 -> 2025

[*/20]
 - Add platform/x86 prefix to commit messages

[PATCH v3 01/20] platform/x86: alienware-wmi: Remove unnecessary check at module exit

[Kurt Borja]

Module initialization fails if platform device fails to register so it's
always not NULL at exit.

[PATCH v3 02/20] platform/x86: alienware-wmi: Move Lighting Control State

[Kurt Borja]

Place Lighting Control State logic next to other attributes of the same
sysfs group.

While at it, rename:

store_control_state()	-> lighting_control_state_store()
show_control_state()	-> lighting_control_state_show()

Replace DEVICE_ATTR() with DEVICE_ATTR_RW() and do a general style
cleanup.

parse_rgb() now takes struct color_platform instead of struct
platform_zone to support upcoming refactor.

[PATCH v3 04/20] platform/x86: alienware-wmi: Improve hdmi_mux, amplifier and deepslp group creation

[Kurt Borja]

Devices with hdmi_mux, amplifier or deepslp quirks create a sysfs group
for each available feature. To accomplish this, helper create/remove
functions were called on module init, but they had the following
problems:

 - Create helpers called remove helpers on failure, which in turn tried
   to remove the sysfs group that failed to be created
 - If group creation failed mid way, previous successfully created groups
   were not cleaned up
 - Module exit only removed hdmi_mux group

To improve this, drop all helpers and let the platform driver manage these
sysfs groups, while controlling visibility with their respective quirks.

[PATCH v3 05/20] platform/x86: alienware-wmi: Improve rgb-zones group creation

[Kurt Borja]

Define zone_attrs statically and initialize zone_attribute_group with
platform driver's .dev_groups.

Drop match_zone() and instead pass a `location` argument to previous
show/store methods to access the correct `zone` LED state. On top of
that rename zone_set() -> zone_store() to be more consistent with sysfs
conventions.

Hi Kurt,

I took patches 1-6 into review-ilpo-next as they seemed very obvious and 
had multiple rev-bys by now.

Please note that I edited this patch to add the new lines after function 
variable declarations in a few functions where they were missing.

[PATCH v3 07/20] platform/x86: alienware-wmi: Add a state container for LED control feature

[Kurt Borja]

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, as well as hdmi, amplifier, deepslp group
visibility methods, 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.

[PATCH v3 08/20] platform/x86: alienware-wmi: Add WMI Drivers

[Kurt Borja]

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 *.

[PATCH v3 10/20] platform/x86: alienware-wmi: Refactor LED control methods

[Kurt Borja]

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.

[PATCH v3 11/20] platform/x86: alienware-wmi: Refactor hdmi, amplifier, deepslp methods

[Kurt Borja]

Refactor show/store methods for hdmi, amplifier, deepslp sysfs groups to
use alienware_wmi_command() instead of alienware_wmax_command() which
uses deprecated WMI methods.

[PATCH v3 13/20] platform/x86: alienware-wmi: Split DMI table

[Kurt Borja]

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.

[PATCH v3 14/20] MAINTAINERS: Update ALIENWARE WMI DRIVER entry

[Kurt Borja]

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,

sorry for taking a bit long to respond. Could you send a v4 series without

I will then try to review this series till the end of this week.

Thanks,
