[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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 will be red when charging and the LED will be green when the
   battery is full.

Moreover, the LED trigger is set to the new trigger, called
"bq27520-0-charging-red-full-green" for Xiaomi Pad2 so the LED will be
red when charging and the LED will be green when the battery is full.

The new LED API led_mc_trigger_event() can be found in the following
URL.

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.
