Support this by adding the external pixel clock to the DT bindings, and selecting the clock automatically at runtime based on the requested mode pixel frequency. The input clock pins to DU channels routing is configurable, but currently hardcoded to connect input clock i to channel i. Signed-off-by: Laurent Pinchart --- Reading git-diff-tree failed
