  25  * SoC dynamic audio power management
  26  *
  27  * We can have up to 4 power domains
  28  *  1. Codec domain - VREF, VMID
  29  *     Usually controlled at codec probe/remove, although can be set
  30  *     at stream time if power is not needed for sidetone, etc.
  31  *  2. Platform/Machine domain - physically connected inputs and outputs
  32  *     Is platform/machine and user action specific, is set in the machine
  33  *     driver and by userspace e.g when HP are inserted
  34  *  3. Path domain - Internal codec path mixers
  35  *     Are automatically set when mixer and mux settings are
  36  *     changed by the user.
  37  *  4. Stream domain - DAC's and ADC's.
  38  *     Enabled when stream playback/capture is started.
