27 * SoC dynamic audio power management

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