The > IN1L Mux control has two settings "A" and "B". That seems clear. So you're saying that you've got a mux on a single physical input which has two inputs? Are you sure that this is actually a mux and not some sort of mode setting that should be in platform data or DT - what do these settinngs actually correspond to? The routes in the driver look like there's two physical pins for each one of IN1L/R which the device can switch between for some reason which does correspond to a mux but that'd more normally be named IN1AL or similar. Though if the left and right side need to be set to the same thing (which IIRC a previous version had code to check for and you did mention in your mail) all the time then why are there two separate muxes anyway?
