  • 3df425f31   OF: PCI: const usage needed by MIPS ... Browse Code »

    On MIPS we want to call of_irq_map_pci from inside

    arch/mips/include/asm/pci.h:extern int pcibios_map_irq(
    const struct pci_dev *dev, u8 slot, u8 pin);
    For this to work we need to change several functions to const usage.

  • 98d9f30c8   pci/of: Match PCI devices to OF nodes dynamically ... Browse Code »

    powerpc has two different ways of matching PCI devices to their
    corresponding OF node (if any) for historical reasons. The ppc64 one
    does a scan looking for matching bus/dev/fn, while the ppc32 one does a
    scan looking only for matching dev/fn on each level in order to be
    agnostic to busses being renumbered (which Linux does on some
    platforms).

    This removes both and instead moves the matching code to the PCI core
    itself. It's the most logical place to do it: when a pci_dev is created,
    we know the parent and thus can do a single level scan for the matching
    device_node (if any).

    The benefit is that all archs now get the matching for free. There's one
    hook the arch might want to provide to match a PHB bus to its device
    node. A default weak implementation is provided that looks for the
    parent device device node, but it's not entirely reliable on powerpc for
    various reasons so powerpc provides its own.
