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