28 * SoC dynamic audio power management

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