[PATCH V3 3/8] ARM: OMAP4: Re-map the CTIs IRQs from MPU to DEBUGSS

From: Jon Hunter <hidden>
Date: 2012-09-10 15:23:41
Also in: linux-omap
Subsystem: arm port, omap hwmod data, omap2+ support, the rest · Maintainers: Russell King, Paul Walmsley, Aaro Koskinen, Andreas Kemnade, Kevin Hilman, Roger Quadros, Tony Lindgren, Linus Torvalds

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].
