OMAP WakeupGen is the interrupt controller extension used along with ARM GIC to wake the CPU out from low power states on external interrupts. The WakeupGen unit is responsible for generating the wakeup event from the incoming interrupts and enable bits. It is implemented in the MPU always ON power domain. During normal operation, WakeupGen delivers the external interrupts directly to the GIC. WakeupGen specification has one restriction as per Veyron version 1.6. It is SW responsibility to program interrupt enabling/disabling coherently in the GIC and in the WakeupGen enable registers. That is, a given interrupt for a given CPU is either enable at both GIC and WakeupGen, or disable at both, but no mix. That's the reason the WakeupGen is implemented as an extension of GIC.
