Don't you want to connect this to something? 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",
You should just use "vdd-micb" instead of DMICVDD.
There is already a SUPPLY DAPM in lpass-va-macro codec.
