From 3098e5b7eebc5dd923562fcbf8acc5990c9e3c64 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Fri, 11 May 2018 09:23:33 -0500 Subject: [PATCH] drm: rcar-du: disable dtc graph-endpoint warnings on DT overlays The rcar DT overlays are missing symetrical remote-endpoint properties in their graph nodes because the remote-endpoint is fixed up at run-time. Disable the dtc 'graph-endpoint' warnings when compiling these overlays. If this becomes a common problem for overlays, then perhaps this check needs to be disabled for all overlays.
