As part of modernizing the platform, we need to implement a proper irqchip in the irqchip subsystem. The IXP4xx irqchip is tightly jotted together with the GPIO controller, and whereas in the past we would deal with this complex logic by adding necessarily different code, we can nowadays modernize it using a hierarchical irqchip. The actual IXP4 irqchip is a simple active low level IRQ controller, whereas the GPIO functionality resides in a different memory area and adds edge trigger support for the interrupts. The interrupts from GPIO lines 0..12 are 1:1 mapped to a fixed set of hardware IRQs on this IRQchip, so we expect the child GPIO interrupt controller to go in and allocate descriptors for these interrupts. For the other interrupts, as we do not yet have DT support for this platform, we create a linear irqdomain and then go in and allocate the IRQs that the legacy boards use. This code will be removed on the DT probe path when we add DT support to the platform. We add some translation code for supporting DT translations for the fwnodes, but we leave most of that for later.

The GPIO part of this block is pretty straight-forward and just uses the generic MMIO GPIO library. The irqchip side of this driver is hierarchical where the main irqchip will receive a processed level trigger in response to the edge detector of the GPIO block, so for this reason the v2 version of the irqdomain API is used (as well as in the parent IXP4xx irqchip) and masking, unmasking and setting up the type on IRQ happens on several levels. Currently this GPIO controller will grab the parent irqdomain using a special function, but as the platform move toward device tree probing, this will not be needed: we can just look up the parent irqdomain from the device tree.
