From e2d5997ffdf5cbf4f7d53584dab2ffc673f50987 Mon Sep 17 00:00:00 2001 From: Philipp Tomsich Date: Fri, 23 Feb 2018 17:38:49 +0100 Subject: core: ofnode: add ofnode_get_parent function The Rockchip video drivers need to walk the ofnode-parrents to find an enclosing device that has a UCLASS_DISPLAY driver bound. This adds a ofnode_get_parent()-function that returns the parent-node.
