26 * SoC dynamic audio power management

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