Patch 4/8 in v4 :) I'm working on it right now to submit asap.

Change in the mvpp2 driver:
-       dev->dev.of_node = port_node;
+       device_set_node(&dev->dev, port_fwnode);
is desired and correct anyway, so as a low-cost change I think it can
be included in this series (which is in fact preparation-to-ACPI
support). I will update the commit message. accordingly.

v1 added all of this, but we agreed that ACPI-specific bits should be
sent separately later, after extending the ACPI Specification.
