S5PC11X: SOUND: Update WM8994 codec gain for Europe
Change gain values in voice call mode
IN1L_VOL(18h, receiver) = -6dB
IN1L_VOL(18h, speaker) = -6dB
IN1R_VOL(1ah, HP_MIC) = -10.5dB
This is requested by Samsung H/W Team.
The reason why voice was clipping problem from codec,
we reduced an analog gain and volume up a digital gain in modem.
And also we can manage to improve an echo/DT problem
from these change.
Change gain values in voice call mode
HPOUT1L_VOL(1ch, HP_MIC) = +3dB
HPOUT1L_VOL(1ch, HP_NO_MIC) = +3dB
HPOUT1R_VOL(1dh, HP_MIC) = +3dB
HPOUT1R_VOL(1dh, HP_NO_MIC) = +3dB
