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.
