[drm:drm_bridge_attach] *ERROR* failed to attach bridge /bus@56220000/dsi_host@56228000 to encoder DSI-89: -517
i used imx8qxp ，mipi output and a bridge chip sn65dsi86 convert to edp ，get this error
the test mode of sn65dsi86 colorbar IS succeed。but mipi signal not work， i check the log find the error Up.
How to solve this problem ，Or how to conduct further investigation，Many thanks
