One nit below, after addressing:

Can we, please, do
if (best_ep)
return best_ep;
if (fwnode && !IS_ERR_OR_NULL(fwnode->secondary))
return fwnode_graph_get_endpoint_by_id(fwnode->secondary, port,
endpoint, flags);
return NULL;
?
This 'if (fwnode && !IS_ERR_OR_NULL(fwnode->secondary))' becomes kinda
idiomatic to the cases when we need to proceed primary followed by the
secondary in cases where it's not already done.
