Hi Rob

This is assuming there's just 1 port and 1 endpoint, but let's be 
specific as the bindings are (first endpoint on port 0):

of_graph_get_endpoint_by_regs(client->dev.of_node, 0, -1);

Note we could ask for endpoint 0 here, but the bindings generally allow 
for more than 1.

I imagine most of the other cases here are the same.

I will do it on new patch-set

quoted

-	for_each_endpoint_of_node(state->dev->of_node, ep_np) {
+	for_each_device_endpoint_of_node(state->dev->of_node, ep_np) {

I would skip the rename.

It is needed to avoid confuse, because new function will add
another endpoint loop.
