right, any plans to have similar functionality generically ? Maybe
something like:


	 * tell PM runtime layer that we can handle runtime
	 * power gating of this device in certain conditions.
	 * Actual power gating will be triggered depending on
	 * PM QoS wakeup requirements.


	if (pm_runtime_will_power_gate(dev))

	if (pm_runtime_has_lost_power(dev))

that might not work always. Specially when you consider that default
register values can change on every silicon release. I guess the above
might be a bit nicer, although a lot more work :-p
