Subject: [PATCH v6 00/11] Add support for PCIe controller to work in endpoint mode on R-Car SoCs
This patch series adds support for PCIe controller on rcar to work in
endpoint mode, this also extends the epf framework to handle base region
for mapping PCI address locally.
Note:
The cadence/rockchip/designware endpoint drivers are build tested only.
