* Recycling of megous v5.16.4 patches The patches were sorted as far as possible. Some patches are renamed according to their place of application. The length of the patch name has been changed to improve readability using the `git format-patch --filename-max-length=75` method. The folder containing the patches will have the name `patches.name` and the corresponding file `series.name` for the convenience of processing and moving them upstream. But the control file remains `series.conf`.

Subject: [PATCH 211/446] 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.
