In order to use the CTI interrupts inconjunction with the DEBUGSS we need to re-map the CTI IRQs to the DEBUGSS HWMOD. The purpose for doing this is so we can create a PMU device based upon the DEBUGSS HWMOD and use the CTI interrupts for routing ARM PMU events for OMAP4430 devices. This is based upon Benoit Cousson's patch [1].
