I take it you're happy to give this your Signed-off-by?

If you define DEBUG when building soc-dapm.c (a define at the top of the
source file will do the trick) then it will be very verbose about the
decisions it's making - that will normally point out the problem.
Probably either one of the input controls is not configured to make a
path from the input pins to the ADC or the input has been mistakenly
marked as disabled.
Otherwise if you post the machine driver and the kernel output with
DEBUG enabled someone might be able to spot something.
