Subject: [PATCH V3 3/8] ARM: OMAP4: Re-map the CTIs IRQs from MPU to DEBUGSS
Date: Mon, 10 Sep 2012 10:23:41 -0500	[thread overview]
Message-ID: <1347290626-21164-4-git-send-email-jon-hunter@ti.com> (raw)
In-Reply-To: <1347290626-21164-1-git-send-email-jon-hunter@ti.com>

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].
