Hi Rob,

After merging the devicetree tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

drivers/gpu/drm/rcar-du/rcar_du_of_lvds_r8a7795.dtb: Warning (graph_endpoint): /fragment@1/__overlay__/port@3/endpoint: graph connection to node '/fragment@0/__overlay__/lvds@feb90000/ports/port@0/endpoint' is not bidirectional
drivers/gpu/drm/rcar-du/rcar_du_of_lvds_r8a7790.dtb: Warning (graph_endpoint): /fragment@1/__overlay__/port@1/endpoint: graph connection to node '/fragment@0/__overlay__/lvds@feb90000/ports/port@0/endpoint' is not bidirectional
drivers/gpu/drm/rcar-du/rcar_du_of_lvds_r8a7790.dtb: Warning (graph_endpoint): /fragment@1/__overlay__/port@2/endpoint: graph connection to node '/fragment@0/__overlay__/lvds@feb94000/ports/port@0/endpoint' is not bidirectional

and over 2000 more :-(

Presumably introduced by commit

  0698fc8b542f ("scripts/dtc: Update to upstream version v1.4.6-21-g84e414b0b5bc")

but not suppressed by commit

  b63caea4b5b5 ("kbuild: disable new dtc graph and unit-address warnings")
