24 * SoC dynamic audio power management
25 *
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.
