ASoC: New enum type: value_enum
This patch introduces a new enum type. In this enum type each enumerated items referred with a value. This new enum type can handle enums encoded in bitfield, or any other weird ways. twl4030 codec has several mux selection register, where the input/output mux is coded in a bitfield. With the normal enum type this type of mux can not be handled in a clean way. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@nokia.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
