+ * 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.
