There doesn't appear to be any build dependency here so can we have an || COMPILE_TEST please and also add to SND_SOC_ALL_CODECS.

Please remove this for upstream.

Remove empty functions, if they can be empty they can just be omitted.

Does the device actually need muting to avoid audio issues? If not it looks like this is something that might be better made a user visible control instead.

I'd expect to see these be part of the set_bias_level() operation.

This looks suspicious... why isn't the power up sequence managed via DAPM?

There's already dev_get_regmap().

This looks like it's just regmap_mmio, why not just use that?

Can we have some defines for this rather than all the magic numbers?

If you use DAPM you shouldn't need to do anything here.
