[PATCH v2 1/5] dt-bindings: adv748x: make data-lanes property mandatory for CSI-2 endpoints

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Niklas Söderlund <niklas.soderlund+renesas@xxxxxxxxxxxx>

The CSI-2 transmitters can use a different number of lanes to transmit
data. Make the data-lanes mandatory for the endpoints describe the
transmitters as no good default can be set to fallback on.
