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.

Isn't this patch missing MPU address ranges? Looking at the OMAP4 TRM Table 2-2 "L3_EMU Memory Space Mapping" it should cover 0x54000000-0x541fffff?
