Sometimes, +this information is more complicated than a cell-index property can +reasonably describe. Thus, each device controlled in such a manner +may contain a "sleep" property which describes these connections. + +The sleep property consists of one or more sleep resources, each of +which consists of a phandle to a sleep controller, followed by a +controller-specific sleep specifier of zero or more cells. + +The semantics of what type of low power modes are possible are defined +by the sleep controller. Some examples of the types of low power modes +that may be supported are: + + - Dynamic: The device may be disabled or enabled at any time. + - System Suspend: The device may request to be disabled or remain + awake during system suspend, but will not be disabled until then. + - Permanent: The device is disabled permanently (until the next hard + reset). + +Some devices may share a clock domain with each other, such that they should +only be suspended when none of the devices are in use. Where reasonable, +such nodes should be placed on a virtual bus, where the bus has the sleep +property. If the clock domain is shared among devices that cannot be +reasonably grouped in this manner, then create a virtual sleep controller +(similar to an interrupt nexus, except that defining a standardized +sleep-map should wait until its necessity is demonstrated). + Appendix A - Sample SOC node for MPC8540 ========================================
