ASoC: sun50i-codec-analog: Internal bias support
Merge series from Samuel Holland <samuel@sholland.org>:
This series adds support for enabling the codec's internal microphone
bias, which is needed on at least some versions of the PinePhone.
Changes in v2:
- Move register update from component probe to device probe
Arnaud Ferraris (2):
ASoC: dt-bindings: sun50i-codec: Add binding for internal bias
ASoC: sun50i-codec-analog: Add support for internal bias
Samuel Holland (1):
arm64: dts: allwinner: pinephone: Enable internal HMIC bias
