Let's avoid adding any more direct PRM or CM register accesses to code
outside the PRM & CM files. Instead let's use higher-level interfaces
that are independent of the underlying OMAP SoC. There are two
motivations. The first is to make the PM code as OMAP SoC-independent as
possible, and low-level register manipulations are SoC-dependent. The
second motivation is that we eventually want to move the PRM and CM code
(and ultimately the PM code) out of arch/arm/mach-omap2 into drivers/.
So for this we'd need some code to control the WKEN bits. Maybe
omap_prm_{disable,enable}_wakeup_from_module() or
pwrdm_{enable,disable}_wakeup_from_module() ?
