[PATCH 0/1] leds: trigger: Add new LED Input events trigger

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

 



Hi All,

While looking into a driver for the backlight for the 3 menu / home / back
capacitive-touch buttons found on the bottom bezel of the Xiaomi Pad 2
tablet I decided rather then to write a custom driver just for this
it would be better to solve this in a generic way which can be reused
on other devices since having such capactive touch buttons on the bottom
bezel is quite normal for somewhat older phones and tablets.

So here is a patch adding a new trigger which turns LEDs on when there is
input (/dev/input/event*) activity and turns them back off again after
there has been no activity for 5 seconds. This trigger can then be used
to control the LEDs backlighting these kind of capactive touch buttons and
it may also be useful to control keyboard backlighting in some cases.

Regards,

Hans
