[RESEND PATCH v3 0/2] Pass resources to pci_create_bus() and fix MIPS PCI resources

From: Deng-Cheng Zhu
Date: Wed Aug 31 2011 - 22:58:18 EST


(Resending the patch set to include more arch maintainers.)

Change the pci_create_bus() interface to pass in available resources to get them
settled down early. This is to avoid possible resource conflicts while doing
pci_scan_slot() in pci_scan_child_bus(). Note that pcibios_fixup_bus() can get
rid of such conflicts, but it's done AFTER scanning slots.

In addition, MIPS PCI resources are now fixed using this new interface.

-- Changes --
v3 - v2:
o Do not do fixups for root buses in pcibios_fixup_bus().
o Skip bus creation when bus resources cannot be allocated.
o PCI domain/bus numbers added to the error info in controller_resources().

v2 - v1:
o Merge [PATCH 1/3] to [PATCH 3/3], so now 2 patches in total.
o Add more info to patch description.
o Fix arch breaks in default resource setup discovered by Bjorn Helgaas.

Deng-Cheng Zhu (2):
PCI: Pass available resources into pci_create_bus()
MIPS: PCI: Pass controller's resources to pci_create_bus() in
pcibios_scanbus()
