[PATCH 00/11] ARM: tegra: Add PCIe device tree support

This patch series adds support for device tree based probing of the PCIe
controller found on Tegra SoCs.

Patches 1 and 2 have already been posted by Grant and Mark respectively
but I've included them here for reference. Both patches are dependencies
for the subsequent patches.

Patches 3, 4 and 5 add support for obtaining the regulators required to
power the PCIe controller from the device tree. Patches 6 and 7 are
required to make some common PCI functions available after the init
phase because the deferred probing will postpone the probing of the PCIe
controller driver until that point.

Patches 8 and 9 make the PCIe controller code available as a driver and
add the corresponding platform devices to the boards that enable PCIe
(Harmony and TrimSlice). Patch 10 adds MSI support and patch 11 finally
adds a device tree binding with documentation.

The code in patch 10 (MSI support) is based on the Vibrante kernel and I
wasn't able to get a proper Signed-off-by or even copyright information.
Perhaps somebody at NVIDIA can find out?
