Subject: [PATCH 4/9] arm64: dts: rockchip: Add power-domain to RK3368 DSI controller

From: Heiko Stuebner <heiko.stuebner@...rry.de>

The DSI controller is also part of the VIO power-domain and it
definitly needs to be on when accessing it to no cause SError
faults, so add the power-domain property to it.
