[PATCH v2] ARM: dts: rockchip: Adding LEDs handling via leds-gpio for the Radxa Rock2 Square

Thu Dec 31 01:13:52 PST 2015


Describe the two user-controllable LEDs on Rock2 Square boards.
All information have been retrieved from the schematics and the vendor
devicetree. The default-triggers mimic the behaviour of the vendor-kernel to
keep functionalities in sync.
