| * SoC dynamic audio power management |
| * |
| * We can have up to 4 power domains |
| * 1. Codec domain - VREF, VMID |
| * Usually controlled at codec probe/remove, although can be set |
| * at stream time if power is not needed for sidetone, etc. |
| * 2. Platform/Machine domain - physically connected inputs and outputs |
| * Is platform/machine and user action specific, is set in the machine |
| * driver and by userspace e.g when HP are inserted |
| * 3. Path domain - Internal codec path mixers |
| * Are automatically set when mixer and mux settings are |
| * changed by the user. |
| * 4. Stream domain - DAC's and ADC's. |
| * Enabled when stream playback/capture is started. |
