I don't think we want to use regmap at all, but we're forced to by soc-core. How do we over-ride that behavior? By writing some nonsense into codec->control_data?

You should use that for your control data, yes - you're not forced to use regmap at all. Like I say we've got a bunch of drivers doing so already.

What's my 'control data'? It's not used in the original codec patch.

The old way wants to go:

snd_soc_update_bits() -> snd_soc_read() -> ab8500_codec_read_reg()

When then calls back into the abx500.

So what 'control data' should I be storing in the codec struct?
