This patch added the support for Xiaomi Pad2 indicator LED. This work
included:
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 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 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.

Lee, I believe this series is ready for merging now ?  I've reviewed
patches 1-2 + 5 and Jacek has reviewed patches 3 + 4.

Patch 5 also has an Acked-by from Sebastian for merging it together
with the rest of the series.

Can you merge patches 1-5 ?

Patch 6 just changes the value of a device-property (the default-trigger
string) and I can merge that through the pdx86 tree independent of
patches 1-5.

Regards,

Hans
