+ * 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.
