Which is required for villager rev boards.

This is open coding SND_SOC_DAPM_REGULATOR_SUPPLY() isn't it?

Yes, agree that SND_SOC_DAPM_REGULATOR_SUPPLY can be used here. As I was
using two different names for
VDD supply property and widget name, got confused. I will re post the
patch, with single name for both and replace with above macro .
