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)
Is this at the pinctrl level or mixer level? If it's at the pinctrl level then it's out of the scope of this driver/binding. It could very well have those signals, just that they aren't routed outside the SoC.

- 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.
