imx53 wakeup source

In my configuration I use imx53 CPU with Linux kernel 2.6.35 (from freescale). It has two wake up sources from the low-power state - RTC and gpio pin (as interrupt).


Is it possible to determine after the wakeup, what was the source (the reason) of the wakeup event?


I looked through imx53 reference manual, but failed to find this information.
