Subject: [PATCH v4 4/9] ASoC: samsung: midas_wm1811: Add headset mic bias
supply support
Some devices use a headset mic bias supply (sometimes referred to as
"ear mic bias") to enable/disable the headset mic.
Add a REGULATOR_SUPPLY widget for this supply which gets the headset-
mic-bias supply and is routed to the Headset Mic switch similar to how
it's done for the other mic bias regulators.
Signed-off-by: Artur Weber <aweber.kernel@...il.com>
