Rockchip DRM driver cannot use the same compare_of() function to
match ports and remote ports (aka encoders) as their OF sub-trees
look different. Add a second compare function to be used when encoders
are added to the component framework and patch the existing users of
the function accordingly.

Russell,

Resurecting this old patch from around Christmas time (bad time for patch
review).

Are you happy enough with this version to re-issue the Ack or do you think
I still need to work on it?
What I'd like to see is the patch reworked, because:
quoted
quoted
+		component_match_add(dev, &match, compare_port, port);
+		/*
+		 * component_match_add keeps a reference to the port
+		 * variable, so we need to keep the reference count
+		 * increment from of_parse_phandle()
+		 */
...
quoted
quoted
+			component_match_add(dev, &match, compare_encoder, remote);
+			/*
+			 * component_match_add keeps a reference to the port
+			 * variable, so we need to keep the reference count
+			 * increment from of_graph_get_remote_port_parent()
+			 */
This problem no longer exists.
Fair enough, I will send a v3 version.

Thanks,
Liviu
