    irqchip: support cascaded VICs · e641b987
    Linus Walleij authored
    This adds support for a VIC to be cascaded off another IRQ.
    On the Integrator/AP logical module IM-PD1 there is a VIC
    cascaded off the central FPGA IRQ controller so this is
    needed for that to work out.
    
    In order for the plug-in board to be able to register all
    the devices with their IRQs relative to the offset of the
    base obtained for the cascaded VIC, the base IRQ number
    is passed back to the caller.
