-/* Expected higher level power calls are:
- * 1 = OFF
- * 2 = STANDBY
- * 3 = ON
- * These will be multiplied by 2 before given to the driver PM code
- * that uses the _PWR_ defines. This allows us to insert defines
- * (most notably _PWR_COMM) allowing more versatile PM.
- * The PM actions:
- * _PWR_OFF     = board support for regulators, clocks, etc so no
- *                power to device.
- * _PWR_STDBY   = board support to put device in reset. Device is
- *                useless but powered.  No communication possible.
- * _PWR_COMM    = Device is powered but in SW standby. Communication
- *                is possible and device retains programming.
- * _PWR_ON      = Full power with active output.
