arm64: dts: renesas: draak: Describe HDMI input (1b1b30a2) · Commits · 戴 / test

Describe HDMI input connector and ADV7612 HDMI decoder installed on R-Car Gen3 Draak board. The video signal routing to the HDMI decoder to the video input interface VIN4 is multiplexed with CVBS input path, and enabled/disabled through on-board switches SW-49, SW-50, SW-51 and SW-52. As the default board switches configuration connects CVBS input to VIN4, leave the HDMI decoder unconnected in DTS. Signed-off-by:
