Hi Bjorn,
I've collected all the patches for PCI Endpoint in this series. This
series contains PCI endpoint fixes and making pci-epf-test more
flexible in terms of mapping PCI_ENDPOINT_TEST regs to any BARs,
work with linkup notification etc.
I've been having most of these patches in my local tree created while
adding support for endpoint in TI's K2G platform. I've also included fix
from others who are trying to use the PCI Endpoint Framework in their
own platforms.
It also contains minor changes in pci/dwc/ like resetting BARs in the
EP controller and providing a page size to pci_epc_mem. I can send this
part separately based on some of your branch if you'd prefer that.
This also contains patches for host side pci_endpoint_test driver
in drivers/misc.
I've pushed the series to pci-endpoint tree, the details of which are
given below.
Thanks
Kishon

----------------------------------------------------------------
PCI: endpoint: for 4.14
PCI endpoint core:
*) Add support for page size to be configurable (for managing address
region within the controller)
*) Add an API to get matching "pci_epf_device_id"
*) Use of_dma_configure() to set initial dma mask of pci_epf device
*) Do not abort if endpoint function drivers have not populated
->remove() callback
pci-epf-test function driver:
*) Add support to poll early for host commands
*) Add support to use _any_ BAR's to map PCI_ENDPOINT_TEST regs
pci_endpoint_test PCI driver:
*) Add support for PCI_ENDPOINT_TEST regs to be mapped to any BAR
*) Add support to provide aligned buffer addresses
*) Enable/Disable MSI using module param
