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.
V5:
* Rebased patch-2 on top of Lorenzo's pci/endpoint branch
* Removed unwanted header files inclusion in patch-5
Applied patches 1,2,5 to pci/endpoint for v5.7, please let me know
if something is missing.
Thanks Lorenzo and Thierry.
Thanks,
Vidya Sagar
Thanks,
Lorenzo
V4:
* Started using threaded irqs instead of kthreads
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
