Hi Bjorn,

Please find the pull request for PCI endpoint support below. I've
also included all the history here.

Changes from v5:
*) remove #syscon-cells property added in v5 and used 
   of_parse_phandle_with_fixed_args
*) fix compilation error in make.cross ARCH=blackfin that was because
   pci_endpoint_test.c driver depends on COMPILE_TEST.

Changes from v4:
*) add #syscon-cells property and used of_parse_phandle_with_args
   to perform a configuration in syscon module (as suggested by
   Rob Herring)
*) Remove unnecessary white space.

Changes from v3:
*) fixed a typo and adapted to https://lkml.org/lkml/2017/3/13/562.

Changes from v2:
*) changed the configfs structure as suggested by Christoph Hellwig. With
   this change the framework creates configfs entry for EP function driver
   and EP controller. Previously these entries have to be created by the
   the user. (Haven't changed the epc core or epf core except for invoking
   configfs APIs to create entries for EP function driver and EP controller.
   That's mostly because the EP function device can still be created by
   directly invoking the epf core API without using configfs).
*) Now the user has to use configfs entry 'start' to start the link.
   This was previously done by the function driver. However in the case of
   multi function EP, the function driver shouldn't start the link.

Changes from v1:
*) The preparation patches for adding EP support is removed and is sent
   separately
*) Added device ID for DRA74x/DRA72x and used it instead of
   using "PCI_ANY_ID"
*) Added userguide for PCI endpoint test function

Major Improvements from RFC:
 *) support multi-function devices (hw supported not virtual)
 *) Access host side buffers
 *) Raise MSI interrupts
 *) Add user space program to use the host side PCI driver
 *) Adapt all other users of designware to use the new design (only
    compile tested. Since I have only dra7xx boards, the new design
    has only been tested in dra7xx. I'd require the help of others
    to test the platforms they have access to).

This is based on
