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

Thierry,

I think one thing that would help here would be to split up this
series into one per subsystem, and to get all the dependencies
merged by the respective maintainers. Preferably, each subsystem
would export a stable branch (perhaps consisting of just these
patches) that I can then merge into the Tegra tree and use as a
basis for the PCIe driver itself. Hopefully this approach will
get more traction on all the non-Tegra changes. Does that sound
like a good plan?

I don't understand. The series is already split up into
per-subsystem patches. I just didn't want to post them separately
so everybody on Cc would be able to see the big picture and the
reason why the patch was required.

There are separate patches that touch the different subsystems, but
they're all scattered throughout the one series, rather than having e.g.:

* a series for the PCI tree
* a series for the ARM core tree
* a series for the OF/DT tree
* a series for the Tegra tree, which indicates it depends on all of those.

I'm wondering if the reason you haven't seen much discussion/Acks from
the maintainers of the non-Tegra trees is because this is a big scary
series that touches a lot of stuff, and it's not necessarily clear for
people unfamiliar with it why they're being CCd on it.
