In some ways, the OMAP4 PRCM register layout is quite different than the OMAP2/3 PRCM register layout. For example, on OMAP2/3, from a register layout point of view, all CM instances were located in the CM subsystem, and all PRM instances were located in the PRM subsystem. OMAP4 changes this. Now, for example, some CM instances, such as WKUP_CM and EMU_CM, are located in the system PRM subsystem. And a "local PRCM" exists for the MPU - this PRCM combines registers that would normally appear in both CM and PRM instances, but uses its own register layout which matches neither the OMAP2/3 PRCM layout nor the OMAP4 PRCM layout. To try to deal with this, introduce some new functions, omap4_cminst* and omap4_prminst*. The former is to be used when writing to a CM instance register (no matter what subsystem or hardware module it exists in), and the latter, similarly, with PRM instance registers. To determine which "PRCM partition" to write to, the functions take a PRCM instance ID argument. Subsequent patches add these partition IDs to the OMAP4 powerdomain and clockdomain definitions. As far as I can see, there's really no good way to handle these types of register access inconsistencies. This patch seemed like the least bad approach. Moving forward, the long-term goal is to remove all direct PRCM register access from the PM code. PRCM register access should go through layers such as the powerdomain and clockdomain code that can hide the details of how to interact with the specific hardware variant. While here, rename cm4xxx.c to cm44xx.c to match the naming convention of the other OMAP4 PRCM files.
