5 The codec class driver is generic and hardware independent code that configures

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

5 AC97 and HD-audio drivers have the automatic power-saving mode.
9 With the automatic power-saving, the driver turns off the codec power
15 The time-out for automatic power-off can be specified via ``power_save``
16 module option of snd-ac97-codec and snd-hda-intel modules. Specify
17 the time-out value in seconds. 0 means to disable the automatic
18 power-saving. The default value of timeout is given via
27 automatic power-save mode with 10 seconds, write to
36 power-down to the active state. These are often hardly to fix, so
