Tegra194 has three (C0, C4 & C5) dual mode PCIe controllers that can 
operate
either in root port mode or in end point mode but only in one mode at 
a time.
Platform P2972-0000 supports enabling endpoint mode for C5 
controller. This
patch series adds support for PCIe endpoint mode in both the driver 
as well as
in DT.
This patch series depends on the changes made for Synopsys DesignWare 
endpoint
mode subsystem that are recently accepted.
@ https://patchwork.kernel.org/project/linux-pci/list/?series=202211
which in turn depends on the patch made by Kishon
@ https://patchwork.kernel.org/patch/10975123/
which is also under review.

V4:
* Started using threaded irqs instead of kthreads

Hi Vidya,

sorry for the bother, may I ask you to rebase the series (after
answering Thierry's query) on top of my pci/endpoint branch please ?

Please resend it and I will merge patches {1,2,5} then.

Sure.
I just sent V5 series rebasing patches on top of your pci/endpoint branch.

Hi,
Sorry to bother you again.
Could you please take a look at V5 series?

Thanks,
Vidya Sagar

V3:
* Re-ordered patches in the series to make the driver change as the 
last patch
* Took care of Thierry's review comments

V2:
* Addressed Thierry & Bjorn's review comments
* Added EP mode specific binding documentation to already existing 
binding documentation file
* Removed patch that enables GPIO controller nodes explicitly as they 
are enabled already
