If the McASP is used with simple-sound-card (as it is the case most of the time) then the port is not present under the node for this device as the card is not using graph. I consider the port (and the #sound-dai-cells if we are here) not part of the McASP hardware description as they are part of the graph or simple-card binding. I'm fine if the port remains here > Peter, > Any other changes I should make? Not much, this already looking good. I would fix the dts files which generates warning/error with this yaml as they are incorrect. -- Péter
