之前用的主线6.6.8，但是用的RGB接口，现在想改成LVDS，DTS配置如下：

panel {
        /*compatible = "shelly,sca07010-bfn-lnn", "simple-panel";*/
        /*compatible = "cdtech,s070pws19hp-fc21", "simple-panel";*/
        compatible = "boe,ev121wxm-n10-1850", "simple-panel";
        /*compatible = "tbs,a711-panel", "panel-lvds";*/
        backlight = <&backlight>;

        panel-timing {
                clock-frequency = <71000000>;   // 71 MHz pixel clock
                hactive = <1280>;
               vactive = <800>;
                hfront-porch = <48>;
                hback-porch = <80>;
                hsync-len = <32>;
               vfront-porch = <3>;
               vback-porch = <10>;
                vsync-len = <4>;
                hsync-active = <0>;   // negative polarity
                vsync-active = <0>;   // negative polarity
                de-active = <1>;
                pixelclk-active = <1>; // rising edge
        };

        port {
            panel_input: endpoint {
                remote-endpoint = <&tcon_lcd0_out_lvds>;
            };
        };
    };

&tcon_lcd0 {
    pinctrl-names = "default";
    pinctrl-0 = <&lcd_lvds0_pins>;
    status = "okay";
};

&tcon_lcd0_out {
    tcon_lcd0_out_lvds: endpoint@0 {
        reg = <0>;
        remote-endpoint = <&panel_input>;
    };
};

系统中有/dev/fb0，但是没有显示，lvds0上面没有信号。求助有没有懂的大佬。多谢！
