ASoC: dapm: deprecate MICBIAS widget type (32902177) · Commits · 戴 / test

Commit ("ASoC: Convert WM8962 MICBIAS to a supply widget", 2011-09-23) says: A supply widget is generally clearer than a MICBIAS widget and a mic bias is just a type of supply so use a supply widget for the MICBIAS. This also avoids confusion with the routing when connected to multiple inputs. but this has never been documented as a policy. Add some comments to make it clear. Signed-off-by:
