25985edc | 28 | * We can have up to 4 power domains |
28683e0f | 29 | * 1. Codec domain - VREF, VMID |
808db4a4 RP |
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. | |
