Subject[PATCH v3 2/3] arm64: dts: renesas: draak: Describe CVBS input
Date
Describe CVBS video input through analog video decoder ADV7180
connected to video input interface VIN4.

The video input signal path is shared with HDMI video input, and
selected by on-board switches SW-53 and SW-54 with CVBS input selected
by the default switches configuration.

Signed-off-by: Jacopo Mondi <jacopo+renesas@jmondi.org>
Reviewed-by: Niklas Söderlund <niklas.soderlund+renesas@ragnatech.se>

v2 -> v3:
- Add comment to describe the shared input video path
- Add my SoB and Niklas' R-b tags
