| 27 | * SoC dynamic audio power management |
| 28 | * |
| 29 | * We can have up to 4 power domains |
| 30 | * 1. Codec domain - VREF, VMID |
| 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. |
