Subject: arm64: dts: rockchip: add gpio-keys to Qnap-TS433
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=c2f60ab28efbc29d9e83fcbb4bfa588e5431c76f;p=u-boot.git

arm64: dts: rockchip: add gpio-keys to Qnap-TS433

The TS433 has 3 buttons, power and copy in the front as well as a reset
pinhole button on the back. The power-button is connected to the embedded
controller while the other two buttons are just gpio connected.

Add the gpio-keys definition for the two buttons we can handle right now.
