Hi, This follows the discussions at Linux Plumbers Conference on PM domains and idle states. In the context of CPU hierarchy, the CPU's idle states may be presented using the property domain-idle-states if the domain is considered as the boundary that powers on/off an individual CPU. To that effect, domain idle states may not be specified but not compatible with what PM domains expects. Hence ignore the idle states that are not "domain-idle-state" compatible. The second patch covers the case, where the hierarchy of PM domains is not powered off in the same context. Currently, a workqueue is scheduled to power off the parent domains in the hierarchy. In case of CPU PM domains, this will not work, since we are running with interrupts disabled. Hence for IRQ safe PM domains, power off the parent domains in the same context as the caller. I understand Ulf is working on some argument changes in the same area of functions. Will work with him to resolve conflicts before the merge. This is based on the tip of Rafel's next.
