This series is sent as RFC since this series is dependent on
[1] (cannot be merged before that series) and to get early review
comments.
I'll also split this series into smaller chunk when I post the
next revision.
This series is about implementing SW defined NTB using
multiple endpoint instances
Add device tree bindings for PCI endpoint function device. The
nodes for PCI endpoint function device should be attached to
PCI endpoint function bus.

pci_epf_driver had two ops for bind and unbind which will be invoked
when an endpoint controller is bound to an endpoint function (using
configfs). Now that endpoint core has support to define an endpoint
function using device tree alone, the bind and unbind ops can be
optional. Make pci_epf_driver

In the case of standard endpoint functions, only one endpoint
