Subject: [PATCH 42/90] arm64: dts: rockchip: rk3399: Number the CDN DP ports
|
|
|
|
Number the input port and add the output port. The binding requires both
|
|
port@0 (VOP input) and port@1 (output), but the node had only a single
|
|
unnamed input port, so every board that enables the DP fails validation:
|
|
|
|
ports: 'port@0' is a required property
|
|
ports: 'port@1' is a required property
|
|
|
|
The output is what a Type-C connector reaches when the DP is behind an
|
|
alternate mode, which no board could describe until now. Endpoint
|
|
numbering inside the input port is unchanged and nothing looks the ports
|
|
up by name, so boards that already enable the DP are unaffected.
