OMAP4 and AM33XX share the same EMIF controller IP. Although there are significant differences in the IP integration due to which AM33XX can't reuse the EMIF driver DVFS similar to OMAP4, it can definitely benefit by reusing the EMIF related macros defined in drivers/memory/emif.h. In the current OMAP PM framework the PM code resides under arch/arm/mach-omap2/. To enable reuse of the register defines move the register defines in the emif header file to include/linux so that both the EMIF driver and the AM33XX PM code can benefit.
