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 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 6 adds MSI support as an IRQ domain.
Patch 7 finally implements device tree support and patches 8, 9 and 10 move
the Harmony and TrimSlice boards over to use information provided in the DTS
to probe the PCIe controller.
