It seems driver expects only one GPIO, but the binding allows any number. Similarly mux-names... Anyway, this does not look like hardware description but rather configuration of driver. What's wrong with input 1 or mux 1 or whatever is there for default? Also: extend the example. Best regards, Krzysztof

I would expect that when this driver is deployed it would mainly be for selecting between things like microphone inputs that are defined and labelled as part of the system hardware design. Using numbered inputs would *work* but it's not great for usability so I do see a use case for labels. Possibly we could figure something out by walking the graph but that seems quite hard, possibly unreasonably so.

I will fix property name and git-log, and re-post v2. Thank you for your help !! Best regards --- Kuninori Morimoto
