[alsa-devel] [PATCH] ASoC: Add regmap as a control type

[Mark Brown]

Allow drivers to set up their own regmap API structures. This is mainly
useful with MFDs where the core driver will have set up regmap at the
minute, though it may make sense to push the existing regmap setup out
of the core into the drivers.
