Currently wcd9320 driver assumes micbias 2 is dedicated to headset and ANC microphones on headset. Allow different microphones share the micbias 2 to support hardware that have shared micbias configuration. If micbias 2 is shared by mic biases other than headset mic, MBHC's ext cable feature will be compromized and also headset removal can make more pop noise. If hardware has dedicated micbias 2 for headset, it's recommanded to disable this feature. Change-Id: I5d5e5c2feb406212dad6d211f49de49e64e1a888 Signed-off-by: Joonwoo Park <joonwoop@codeaurora.org>
