    [ARM] Orion: fix ->map_irq() PCIe bus number check · 92b913b0
    Lennert Buytenhek authored
    The current orion5x board ->map_irq() routines check whether a
    given bus number lives on the PCIe controller by comparing it with
    the PCIe controller's primary bus number.  This doesn't work in
    case there are multiple buses in the PCIe domain, i.e. if there
    exists a PCIe bridge on the primary PCIe bus.
    
    This patch adds a helper function (orion5x_pci_map_irq()) that
    returns the IRQ number for the given PCI device if that device has
    a hard-wired IRQ, or -1 otherwise, and makes each board's
    ->map_irq() function use this helper function.
