DA7210 has three line inputs (AUX1 Left, AUX1 Right and AUX2) and a stereo MIC. This patch adds gain controls for MIC, AUX1, AUX2 as well as INPGA. It also adds a control to set MIC BIAS voltage.

Signed-off-by: Ashish Chavan ashish.chavan@kpitcummins.com Signed-off-by: David Dajun Chen dchen@diasemi.com --- Changes since v2: - Removed static enable of mic and aux, as now DAPM will take care of that

Changes since v1: - Removed explicit setting of default gains - Removed control to set mic bias voltage --- sound/soc/codecs/da7210.c | 44 ++++++++++++++++++++++++++++++++++++++++++++ 1 files changed, 44 insertions(+), 0 deletions(-)
