5 The codec class driver is generic and hardware independent code that configures
6 the codec, FM, MODEM, BT or external DSP to provide audio capture and playback.
11 Each codec class driver *must* provide the following features:-
13 1. Codec DAI and PCM configuration
14 2. Codec control IO - using RegMap API
16 4. Codec audio operations
20 Optionally, codec drivers can also provide:-
