On the newer SoCs such as the H3 and A64 this is set by default to transfer a 0 after each sample in each slot. However the A10 and A20 SoCs that this driver was developed on had a default setting where it padded the audio gain with zeros.
This isn't a problem whilst we have only support for 16bit audio but with larger sample resolution rates in the pipeline then SEXT bits should be cleared so that they also pad at the LSB. Without this the audio gets distorted.

If anything, I'd like to have less regmap_fields rather than more of them. This is pretty easy to add to one of the callbacks, especially since the field itself has been completely reworked from one generation to the other.
