Needs a specific soc table.
Hi Eric, thanks for response, but it does not fix the issue for me. hdmi on mt7623 is DPI not DSI. There is already a mt7623 specific routing-table defined (one for DPI/HDMI and one for external=DSI/MIPI): https://elixir.bootlin.com/linux/latest/source/drivers/gpu/drm/mediatek/mtk_drm_drv.c#L74 maybe it can be included or compared with the "default" route? regards Frank _______________________________________________ Linux-mediatek mailing list Linux-mediatek@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-mediatek
