[PATCH v5 2/2] arm64: dts: renesas: salvator-x: Add ADV7482 support

Kieran Bingham kbingham at kernel.org
Wed Jun 14 12:58:13 PDT 2017


From: Kieran Bingham <kieran.bingham+renesas at ideasonboard.com>

The Salvator boards use an ADV7482 receiver for HDMI and CVBS inputs.

Provide ADV7482 node on the i2c4 bus, along with connectors for the
hdmi and cvbs inputs, and link to the csi20 and csi40 nodes as outputs.

Signed-off-by: Kieran Bingham <kieran.bingham+renesas at ideasonboard.com>

v4:
 - dt: Rebase to dts/renesas/salvator-x.dtsi
 - dt: Use AIN0-7 rather than AIN1-8

v5:
 - dt: Move to salvator-common.dtsi
