Subject: of: property: Add in-ports/out-ports support to of_graph_get_port_parent()
From: Saravana Kannan <saravanak@xxxxxxxxxx>
commit 8f1e0d791b5281f3a38620bc7c57763dc551be15 upstream.
Similar to the existing "ports" node name, coresight device tree bindings
have added "in-ports" and "out-ports" as standard node names for a
collection of ports.
Add support for these name to of_graph_get_port_parent() so that
remote-endpoint parsing can find the correct parent node for these
coresight ports too.
