When I build for an old imx53 platform I see the same as the test robot saw before: arm-buildroot-linux-gnueabihf-ld: drivers/gpu/drm/imx/ipuv3/parallel-display.o: in function `imx_pd_bind': parallel-display.c:(.text+0xb8): undefined reference to `drm_bridge_connector_init' Selecting DRM_DISPLAY_HELPER for DRM_IMX_PARALLEL_DISPLAY fixes the build.
