From mboxrd@z Thu Jan 1 00:00:00 1970 From: jon-hunter@ti.com (Jon Hunter) Date: Mon, 10 Sep 2012 10:23:41 -0500 Subject: [PATCH V3 3/8] ARM: OMAP4: Re-map the CTIs IRQs from MPU to DEBUGSS In-Reply-To: <1347290626-21164-1-git-send-email-jon-hunter@ti.com> References: <1347290626-21164-1-git-send-email-jon-hunter@ti.com> Message-ID: <1347290626-21164-4-git-send-email-jon-hunter@ti.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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].
