[alsa-devel] [RFC PATCH 01/34] ASoC: dt-bindings: Add a separate compatible for the A64 codec

The digital codec in the A64 is largely compatible with the one in the
A33, with two changes:
- It is missing some muxing options for AIF1/2/3 (not currently
supported by the driver)
- It does not have the LRCK inversion issue that A33 has

To fix the Left/Right channel inversion on the A64 caused by the A33
LRCK fix, we need to introduce a new compatible for the codec in the
A64.
