This patch series adds support for device tree based probing of the PCIe
controller found on Tegra SoCs.
Patches 1 and 2 keep the pci_fixup_irqs() and ARM-specific
pci_common_init() functions around after init. This is required to
support driver probe deferral, which may cause built-in drivers to be
probed after __init data has already been freed.
Patch 3 allows a driver's probe function to pass per-controller private
data when calling the pci_common_init() function.
Patch 4 is trivial and has already been Acked-by: Stephen Warren before.
Patch 5 adds a flag to mark a struct resource as defining a PCI
configuration space. The flag will be used subsequently to differentiate
between memory-mapped I/O regions and PCI configuration space.
Patch 6 rewrites PCIe support as a driver and switches the Harmony and
TrimSlice boards to add the proper platform device instead of calling
the tegra_pcie_init() function. Patch 7 adds MSI support as an IRQ
domain.
Patches 8 and 9 add code to support the new PCIe controller binding used
by patch 10 to instantiate the controller from DT.
