Hi All,
Here is v8 of Kate's series to add support for Xiaomi Pad2 indicator LED.
I believe this is ready for merging now. Patch 6/7 has an Acked-by from
Sebastien for merging this patch through the leds tree since it depends
on the earlier patches. LEDs tree maintainers please merge patches 1-6,
then patch 7 can be merged through the pdx86 tree indepdently.
This work includes:
1. Added the KTD2026 swnode description to describe the LED controller.
2. Migrated the original driver to fwnode to support x86 platform.
3. Support for multi-color LED trigger event.
4. The LED shows orange when charging and the LED shows green when the
battery is full.
Moreover, the LED trigger is set to the new trigger, called
"bq27520-0-charging-orange-full-green" for Xiaomi Pad2 so the LED shows
orange when charging and the LED shows green when the battery is full.

Changes in v8:
1. New bugfix: "leds: rgb: leds-ktd202x: Initialize mutex earlier"
2. Make charging_orange_full_green triggers set the colors in RGB order
3. Modify the Pad2 ktd202x fwnode to have the colors in RGB order
Changes in v7:
1. Platform: x86-android-tablets: other: Add swnode for Xiaomi pad2
indicator LED was included in Hans' branch.
2. Included the tags from the previous version in the commit message.
3. Fixed the comma issue for the structure initialiser.
Changes in v6:
1. The I2C ID table was moved to a separate patch.
2. The LED shows orange when charging.
3. The trigger name was renamed to charging-orange-full-green.
4. The default trigger of Xiaomi Pad2 is
"bq27520-0-charging-orange-full-green".
Changes in v5:
1. Fix swnode LED color settings.
2. Improve the driver based on the comments.
3. Introduce a LED new API- led_mc_trigger_event() to make the LED
color can be changed according to the trigger.
4. Introduced a new trigger "charging-red-full-green". The LED will be
red when charging and the LED will be green when the battery is full.
5. Set the default trigger to "bq27520-0-charging-red-full-green" for
Xiaomi Pad2.
Changes in v4:
1. Fix double casting.
2. Since force casting a pointer value to int will trigger a compiler
warning, the type of num_leds was changed to unsigned long.
Changes in v3:
1. Drop the patch "leds-ktd202x: Skip regulator settings for Xiaomi
pad2"
Changes in v2:
1. Typo and style fixes.
2. The patch 0003 skips all the regulator setup for Xiaomi pad2 since
KTD2026 on Xiaomi pad2 is already powered by BP25890RTWR. So, the
sleep can be removed when removing the module.
Regards,
Hans
