I already posted a similar patch[0] as part of a larger series to bring
DT support to Tegra PCIe back in July. I suppose what you have must be
something pretty close to that. Most of the stuff that had me occupied
since then should be done soon and I was planning on resurrecting the
series one of these days.

Thanks for the reference. I've submitted my patch, it's along the lines of =
your
existing patch.

I'm happy to take the best bits from both, drop mine, etc.
