Phandles are the fancy device tree name for "pointer to another node". To create a phandle property, we most likely want to reference to the node we're pointing to by its path. So create a helper that allows us to do so. Signed-off-by: Alexander Graf <agraf@suse.de> --- device_tree.c | 7 +++++++ device_tree.h | 2 ++ 2 files changed, 9 insertions(+), 0 deletions(-)
