Looks like some thing is not handled properly in driver that is causing this irq 53, we had similar issue in OMAP3 with irq33. I will have to discuss this with Sekhar, he is on vacation this week. Will keep you updated as soon as I get more info into this. For now can we put a big disclaimer on this (TBD) and move forward? - this is just a request.
