Subject: [PATCH v6 0/7] Add SR-IOV support in PCIe Endpoint Core
Date:   Mon, 17 May 2021 13:17:16 +0530
Message-ID: <20210517074723.10212-1-kishon@ti.com>

Precedence: bulk

Patch series
*) Adds support to add virtual functions to enable endpoint controller
   which supports SR-IOV capability
*) Add support in Cadence endpoint driver to configure virtual functions
*) Enable pci_endpoint_test driver to create pci_device for virtual
   functions

v1 of the patch series can be found at [1]
v2 of the patch series can be found at [2]
v3 of the patch series can be found at [3]
v4 of the patch series can be found at [4]
v5 of the patch series can be found at [5]

Here both physical functions and virtual functions use the same
pci_endpoint_test driver and existing pcitest utility can be used
to test virtual functions as well.

Changes from v5:
*) Rebased to 5.13-rc1

Changes from v4:
*) Added a fix in Cadence driver which was overwriting BAR configuration
   of physical function.
*) Didn't include Tom's Acked-by since Cadence driver is modified in
   this revision.

Changes from v3:
*) Fixed Rob's comment and added his Reviewed-by as suggested by him.

Changes from v2:
*) Fixed DT binding documentation comment by Rob
*) Fixed the error check in pci-epc-core.c

Changes from v1:
*) Re-based and Re-worked to latest kernel 5.10.0-rc2+ (now has generic
   binding for EP)
