This patch series
*) add PCI endpoint core layer
*) modify designware and dra7xx driver to be configured in EP mode
*) add a PCI endpoint *test* function driver and corresponding host
driver
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).
