The Radxa E20C has three gpio leds and one gpio button.

This series adds dt-binding, driver support, DT node in SoC .dtsi and
gpio-keys and gpio-leds nodes in board DT to support the leds and user
button.

This series builds on top of the "rockchip: Add support for maskrom
button on Radxa E20C" series [1].

Board schematics for Radxa E20C can be found at [2].
