[PATCHv11 5/8] ARM: OMAP2+: mux: add support for PAD wakeup interrupts

[Tony Lindgren]

* Tero Kristo <t-kristo at ti.com> [111212 09:44]:
> OMAP mux now parses active wakeup events from pad registers and
> calls corresponding hwmod ISRs once a wakeup is detected. This is
> accomplished by registering an interrupt handler for PRCM IO event,
> which is raised every time the HW detects wakeups.

This will need to be updated once we are using the pinctrl
framework, for now this looks good to me:
