Hi,
this is v2 from my patchset that add support for the TAS2505 to the tlv320aic32x4 driver.
kind regards,
Claudius
Changes from v1:
- clarified commit message of first patch, which add the type value to the struct
- removed unnecessary code to put and get speaker volume
- removed 'Gain' from 'HP Driver Playback Volume' control
- fixed rebase issues
