Subject: [PATCH 0/5] Add support for PCIe controller to work in endpoint mode on R-Car SoCs.
Date: Wed,  6 Nov 2019 19:36:04 +0000	[thread overview]
Message-ID: <20191106193609.19645-1-prabhakar.mahadev-lad.rj@bp.renesas.com> (raw)

From: "Lad, Prabhakar" <prabhakar.mahadev-lad.rj@bp.renesas.com>

This patch series adds support for PCIe controller on rcar to work in endpoint mode,
this also extends the epf framework to handle multiple outbound regions.

Note: 
The cadence/rockchip/designware endpoint drivers are build tested only.

Endpoint configuration:
$ cd /sys/kernel/config/pci_ep
$ mkdir functions/pci_epf_test/func1
$ echo 0x1912 > functions/pci_epf_test/func1/vendorid
$ echo 0x002d > functions/pci_epf_test/func1/deviceid
$ echo 32 > functions/pci_epf_test/func1/msi_interrupts
$ ln -s functions/pci_epf_test/func1/ controllers/fe000000.pcie_ep/
$ echo 1 > controllers/fe000000.pcie_ep/start
