Unfortunately, it\nbroke the at91 platform which assumed that pm_ops-\u003eprepare() would be called\nbefore suspending devices.\n\nat91 used pm_ops-\u003eprepare() to get notified of the target system sleep state,\nso that it could use this information while suspending devices. However, with\nthe current suspend code ordering pm_ops-\u003eprepare() is called too late for\nthis purpose.
