From c7dad45f351e9bea8ebaa974f01b01c8f69432b4 Mon Sep 17 00:00:00 2001 From: Jon Hunter Date: Sun, 23 Sep 2012 17:28:28 -0600 Subject: [PATCH] ARM: OMAP3: hwmod data: Add debugss HWMOD data To enable PMU with runtime PM support on OMAP3 devices we need to be able to dynamically enable and disable the debug sub-system at runtime. By adding HWMOD data for the debug sub-system for OMAP3, we can build the PMU device using the debug sub-system HWMOD and control this power domain using runtime PM.
