Yes, it can be dropped as it is not wired on the Carrier. I will send a patch dropping this. Cheers, Biju

Is dt binding check allows conditional macros? Based on switch position audio signal ssi0 is routed to Audio codec Or ssi1 is routed to HDMI audio port The former one does not use graph where as latter one uses audio graph How do I describe this in bindings? like dts, something like below supported in dt bindings?? #if X Audio codec #else HDMI Audio #endif Cheers, Biju
