Subject: [PATCH 249/515] ASoC: dt-bindings: sun50i-codec: Add binding for
|
|
internal bias
|
|
|
|
In order to properly bias headset microphones, there should be a
|
|
resistor between pins HBIAS and MICDET. This can be an external
|
|
resistor, but the codec also provides an internal 2.2K resistor which
|
|
can be enabled by a register.
|
|
|
|
This patch adds a device-tree property to the sun50i-codec-analog driver
|
|
to take advantage of this feature.
