b7d2a803 25 * SoC dynamic audio power management
808db4a4 26 *
25985edc 27 * We can have up to 4 power domains
28683e0f 28 * 1. Codec domain - VREF, VMID
808db4a4
RP		 29 * Usually controlled at codec probe/remove, although can be set
30 * at stream time if power is not needed for sidetone, etc.
31 * 2. Platform/Machine domain - physically connected inputs and outputs
32 * Is platform/machine and user action specific, is set in the machine
33 * driver and by userspace e.g when HP are inserted
34 * 3. Path domain - Internal codec path mixers
35 * Are automatically set when mixer and mux settings are
36 * changed by the user.
37 * 4. Stream domain - DAC's and ADC's.
38 * Enabled when stream playback/capture is started.
