Currently CIF channels are overridden based on mono/stereo settings. This can be problematic for multi-channel use cases or the cases where user is intentionally overriding channels through mixer control. In such cases hard coding based on CIF mono/stereo settings can result in wrong behavior. Following are the changes in current patch, * Decouple CIF mono/stereo and CIF channel settings. It means that, user can override audio channels and CIF settings independently. Also these controls are provided for both playback and capture paths. * For ADMAIF, channel overrides are provided for both audio and client channels in both playback and capture paths. * For I2S, separate channel overrides for client channels is not needed in playback and capture paths. Hence a common client channel override control is provided. However for audio channels it is similar to the controls provided for ADMAIF. * Similar to channels, for I2S, audio bit format control is updated and provided separate controls in playback and capture paths. * "None" option is removed for mono/stereo to match HW register spec. Earlier channel was hard coded based on this. * For I2S, audio channels are used for CIF configuration and for the slot control client channels are used (earlier audio channels were getting used for slot control) * For upstream, we are standardizing mixer control names. For now, only relevant controls are updated. Going forward we need to take similar approach for all controls/modules. This needs to be reflected in test scripts and documentation as well.
