The PCI core allows -architectures to implement the pcibios_add_bus() and -pcibios_remove_bus() for this purpose. This commit therefore extends -the hw_pci and pci_sys_data structures of the ARM PCI core to allow -PCI drivers to register ->add_bus() and ->remove_bus() in hw_pci, -which will get called when a bus is added or removed from the system. - -This will be used for example by the Marvell PCIe driver to connect a -particular PCI bus with its corresponding MSI chip to handle Message -Signaled Interrupts. - -Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> -Reviewed-by: Thierry Reding <thierry.reding@gmail.com> -Acked-by: Russell King <rmk+kernel@arm.linux.org.uk> -Tested-by: Daniel Price <daniel.price@gmail.com> -Tested-by: Thierry Reding <thierry.reding@gmail.com> ---- - arch/arm/include/asm/mach/pci.h | 4 ++++ - arch/arm/kernel/bios32.c | 16 ++++++++++++++++ - 2 files changed, 20 insertions(+) - ---- a/arch/arm/include/asm/mach/pci.h -+++ b/arch/arm/include/asm/mach/pci.h -@@ -35,6 +35,8 @@ struct hw_pci { - resource_size_t start, - resource_size_t size, - resource_size_t align); -+ void (*add_bus)(struct pci_bus *bus); -+ void (*remove_bus)(struct pci_bus *bus); - }; - - /* -@@ -62,6 +64,8 @@ struct pci_sys_data { - resource_size_t start, - resource_size_t size, - resource_size_t align); -+ void (*add_bus)(struct pci_bus *bus); -+ void (*remove_bus)(struct pci_bus *bus); - void *private_data; /* platform controller private data */ - }; - ---- a/arch/arm/kernel/bios32.c -+++ b/arch/arm/kernel/bios32.c -@@ -363,6 +363,20 @@ void pcibios_fixup_bus(struct pci_bus *b - } - EXPORT_SYMBOL(pcibios_fixup_bus); - -+void pcibios_add_bus(struct pci_bus *bus) -+{ -+ struct pci_sys_data *sys = bus->sysdata; -+ if (sys->add_bus) -+ sys->add_bus(bus); -+} -+ -+void pcibios_remove_bus(struct pci_bus *bus) -+{ -+ struct pci_sys_data *sys = bus->sysdata; -+ if (sys->remove_bus) -+ sys->remove_bus(bus); -+} -+ - /* - * Swizzle the device pin each time we cross a bridge.
