[alsa-devel] [PATCH v2 5/6] ASoC: omap: n810: HS mic is not working, add a widget for it with comment

[Peter Ujfalusi]

The bias for the analog HS microphone is coming from Retu/Vilma chip and
we do not have control over it, yet.

For clarity, add a new DAPM_MIC widget for the HS mic and document the
current state.
