[PATCH 0/5] PCI: tegra: Add Tegra264 support

[Thierry Reding <thierry.reding@kernel.org>]

From: Thierry Reding <treding@nvidia.com>

Hi,

this series adds support for the PCIe controllers found on the Tegra264
SoC. There are six instances, one of which is for internal purposes only
and the other five are general purpose.

The first two patches in the series add the BPMP support needed to power
up/down the PCI link. Patch 3 contains the device tree bindings for the
PCIe controller and patch 4 adds the driver. Finally, patch 5 adds DT
nodes for the controllers found on the Tegra264 SoC.

Regarding merging these patches, I think ideally I'd want to pick up the
PCI driver patch into the Tegra tree because there is a build dependency
on patches 1 and 2. Furthermore, patch 1 depends on another patch that's
already in the Tegra tree, and there will be conflicts if it is merged
in another tree. Alternatively I can provide a stable branch with
patches 1 and 2 for the PCI maintainers to pull in.

Let me know how you'd like to handle this.

Thanks,
Thierry
