[alsa-devel] [PATCH 00/19] ASoC: cleanup Codec reg_cache

[Kuninori Morimoto]

Hi Mark, Lars-Peter

These are 3rd step patches.
Some Codec drivers are using Codec reg_cache, or
using get_regmap.

1st, only 3 drivers are using Codec reg_cache.
ALSA SoC has reg_cache common driver for these 3 drivers,
Becase it is not a big code, We can have it on each drivers,
and remove/cleanup reg_cache code from ALSA SoC.

2nd, only 2 drivers are using snd_soc_write/read
without using regmap/reg_cache.
(snd_soc_write/read will use regmap function
or .write/.read callback)
Because of it, we need to have .write/.read callback
on Codec driver. We can remove these if this 2 drivers
call its own write/read function directly.

3rd, some drivers want to use its own regmap.
Because of it, Codec driver has .get_regmap callback.
But, we can replace it by using snd_soc_component_init_regmap().
