From 02df94d98ff837074788ce921edf67707dbad404 Mon Sep 17 00:00:00 2001 From: Martin Kepplinger-Novakovic Date: Wed, 21 Jan 2026 11:26:07 +0100 Subject: [PATCH] drm/imx: parallel-display: add DRM_DISPLAY_HELPER for DRM_IMX_PARALLEL_DISPLAY 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.
