of/pci: Add of_pci_parse_bus_range() function

2013-05-19T20:30:10Z

This function can be used to parse a bus-range property as specified by device nodes representing PCI bridges. Signed-off-by: Thierry Reding Signed-off-by: Jason Cooper

of/pci: Add of_pci_get_devfn() function

2013-05-19T20:30:10Z

This function can be used to parse the device and function number from a standard 5-cell PCI resource. PCI_SLOT() and PCI_FUNC() can be used on the returned value obtain the device and function numbers respectively.

OF: PCI: const usage needed by MIPS

2012-05-21T13:31:48Z

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.

pci/of: Match PCI devices to OF nodes dynamically

2011-06-07T23:08:17Z

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.

of/pci: move of_irq_map_pci() into generic code

2011-02-04T18:46:50Z

There is a tiny difference between PPC32 and PPC64. Microblaze uses the PPC32 variant.
