Subject: [PATCH 00/11] ASoC/MFD: twl4030 codec local register cache removal

Hi,

After the twl6040 codec, now it is time for the twl4030 codec driver to loose
it's local reg cache and let the MFD core's regmap to take care of the caching.

We have different functions behind of the 0x49 i2c address in twl (where the
audio registers can be found between 0x01 - 0x49). I mark all non audio
registers as volatile for now to avoid any side effect of the caching. Gradually
other functionalities can also move their caching to regmap to simplify the code.

I have included couple of clean up patches after the local regcache removal to
the series to freshen up the code a bit.

Regards,
Peter
