Subject: [PATCH 096/389] arm64: dts: sun50i-a64-pinephone: Enable internal
|
||
|
|
HMIC bias
|
||
|
|
|
||
|
|
Revisions 1.0 and 1.1 of the PinePhone mainboard do not have an external
|
||
|
|
resistor connecting HBIAS to MIC2. Enable the internal resistor to
|
||
|
|
provide the appropriate mic bias.
|
||
