+/*! @enum IOPMPowerFlags
+ @abstract Bits are used in defining capabilityFlags, inputPowerRequirements, and outputPowerCharacter in the IOPMPowerState structure.
+ @discussion These bits may be bitwise-OR'd together in the IOPMPowerState capabilityFlags field, the outputPowerCharacter field, and/or the inputPowerRequirement field.
+
+ The comments clearly mark whether each flag should be used in the capabilityFlags field, outputPowerCharacter field, and inputPowerRequirement field, or all three.
+
+ The value of capabilityFlags, inputPowerRequirement or outputPowerCharacter may be 0. Most drivers implement their 'OFF' state, used when asleep, by defininf each of the 3 fields as 0.
+
+ The bits listed below are only the most common bits used to define a device's power states. Your device's IO family may require that your device specify other input or output power flags to interact properly. Consult family-specific documentation to determine if your IOPower plane parents or children require other power flags; they probably don't.
+
+ @constant kIOPMPowerOn Indicates the device is on, requires power, and provides power. Useful as a: Capability, InputPowerRequirement, OutputPowerCharacter
+
+ @constant kIOPMDeviceUsable Indicates the device is usable in this state. Useful only as a Capability
+
+ @constant kIOPMLowPower
+ Indicates device is in a low power state. May be bitwis-OR'd together
+ with kIOPMDeviceUsable flag, to indicate the device is still usable.
+
+ A device with a capability of kIOPMLowPower may:
+ Require either 0 or kIOPMPowerOn from its power parent
+ Offer either kIOPMLowPower, kIOPMPowerOn, or 0 (no power at all)
+ to its power plane children.
+
+ Useful only as a Capability, although USB drivers should consult USB family documentation for other valid circumstances to use the kIOPMLowPower bit.
+
+ @constant kIOPMPreventIdleSleep
+ In the capability field of a power state, disallows idle system sleep while the device is in that state.
+
+ For example, displays and disks set this capability for their ON power state; since the system may not idle sleep while the display (and thus keyboard or mouse) or the disk is active.
+
+ Useful only as a Capability.
+
+ @constant kIOPMSleepCapability
+ Used only by certain IOKit Families (USB). Not defined or used by generic Power Management. Read your family documentation to see if you should define a powerstate using these capabilities.
+
+ @constant kIOPMRestartCapability
+ Used only by certain IOKit Families (USB). Not defined or used by generic Power Management. Read your family documentation to see if you should define a powerstate using these capabilities.
+
+ @constant kIOPMSleep
+ Used only by certain IOKit Families (USB). Not defined or used by generic Power Management. Read your family documentation to see if you should define a powerstate using these capabilities.
+
+ @constant kIOPMRestart
+ Used only by certain IOKit Families (USB). Not defined or used by generic Power Management. Read your family documentation to see if you should define a powerstate using these capabilities.
