On VF6xx models, almost all peripherals can be used by either of the two CPU's, the Cortex-A5 or the Cortex-M4. The interrupt router routes the peripheral interrupts to the configured CPU. This IRQ chip driver configures the interrupt router to route the requested interrupt to the CPU the kernel is running on. The driver makes use of the irqdomain hierarchy support. The parent is given by the device tree. This should be one of the two possible parents either ARM GIC or the ARM NVIC interrupt controller. The latter is currently not yet supported. Note that there is no resource control mechnism implemented to avoid concurrent access of the same peripheral. The user needs to make sure to use device trees which assign the peripherals orthogonally. However, this driver warns the user in case the interrupt is already configured for the other CPU. This provides a poor man's resource controller.

This code triggers the PGC powerdown sequence to disable the GPU/VPU isolation cells and gate power and then disables the PU regulator. To reenable, the reverse powerup sequence is triggered after the PU regulator is enabled again. The GPU and VPU devices in the PU power domain temporarily need to be clocked during powerup, so that the reset machinery can work.
