RK3399点edp屏报错问题

点dts报如下错误:

[    2.744420] [drm:rockchip_dp_bind] *ERROR* failed to find panel
[    2.744455] rockchip-drm display-subsystem: failed to bind ff970000.edp (ops rockchip_dp_component_ops): -517
[    2.744737] rockchip-drm display-subsystem: master bind failed: -517

原因:1.由于dts配置中edp节点里面compatible = "panel-simple";这个没有起到作用,需要添加一个匹配。如:compatible ="auo,b125han03", "panel-simple"。2.由于enable-gpios 配置错误或者被其他节点占用。3.没有配置背光节点。
