This won't do anything as-is. I can't see any references to DMICVDD which might be failing to resolve in the current sound/soc/qcom.

The connection is being done to "VA DMIC"through audio routing in board specific dts file. Will post the changes once the main dts patches are landed. Ex:- &sound { DMICVDD-supply = <&pp1800_l2c>; audio-routing = "IN1_HPHL", "HPHL_OUT", "IN2_HPHR", "HPHR_OUT", "AMIC1", "MIC BIAS1", "AMIC2", "MIC BIAS2", "VA DMIC0", "DMICVDD", "VA DMIC1", "DMICVDD", "VA DMIC2", "DMICVDD", "VA DMIC3", "DMICVDD", ..... ..... };

Will test with vdd-micb DAPM. if that works, I think we can drop this patch. >> ..... >> >> ..... >> >> }; >> >>
