* SoC dynamic audio power management
26
* We can have up to 4 power domains
27
* 1. Codec domain - VREF, VMID
28
* Usually controlled at codec probe/remove, although can be set
29
* at stream time if power is not needed for sidetone, etc.
30
* 2. Platform/Machine domain - physically connected inputs and outputs
31
* Is platform/machine and user action specific, is set in the machine
32
* driver and by userspace e.g when HP are inserted
33
* 3. Path domain - Internal codec path mixers
34
* Are automatically set when mixer and mux settings are
35
* changed by the user.
36
* 4. Stream domain - DAC's and ADC's.
37
* Enabled when stream playback/capture is started.
