Since this affects the routing these should be DAPM controls. Otherwise you might run into issues with a path being powered down even if it is used.
I think the naming of these controls needs work.
This presently doesn't actually affect DAPM. You are changing whether the output of the left ADC will be treated as the left or right channel on the AIF, but in both cases the AIF and Left ADC will be powered up.
This might change if the driver was changed to the newer style AIF hookup, although I haven't looked in detail to see if it would make sense to use a single widget for the AIF or one for each channel as per the Arizona devices.
