In the omap_device PM domain callbacks, use omap_device idle/enable to automatically manage device idle states during system suspend/resume. If an omap_device has not already been runtime suspended, the ->suspend_noirq() method of the PM domain will use omap_device_idle() to idle the HW after calling the driver's ->runtime_suspend() callback. Similarily, upon resume, if the device was suspended during ->suspend_noirq(), the ->resume_noirq() method of the PM domain will use omap_device_enable() to enable the HW and then call the driver's ->runtime_resume() callback. If a device has already been runtime suspended, the noirq methods of the PM domain leave the device runtime suspended by default. However, if a driver needs to runtime resume a device during suspend (for example, to change its wakeup settings), it may do so using pm_runtime_get* in it's ->suspend() callback.
