Re: [PATCH v1 1/1] arm64: dts: qcom: x1e80100-lenovo-yoga-slim7x: enable MICs LDO

[Aleksandrs Vinarskis]

You are right, this is probably too 'dirty' fix.
I did some more digging, and found the root cause of the problem -
MICs were not configured in audio routings, even though vreg was
already binded to lpass_macro. Will send v2.

Thanks,
Alex
