后面在编译时出现报错，报错信息提示为phandle_references错误，在设备树文件中有对不存在的节点或标签的引用。需要去配置lvds2link_pins_a和lvds2link_pins_b。于是我在sun8iw20p1-t113-100ask-t113-pro.dts这个文件中去写入这两个引脚的信息。如下：
lvds2link_pins_a: lvds2link@0 {
allwinner,pins = "PD0", "PD1", "PD2", "PD3", "PD4", "PD5", "PD8", "PD9", "PD6", "PD7",
"PD10", "PD11", "PD12", "PD13", "PD14", "PD15", "PD18", "PD19", "PD16", "PD17";
allwinner,pname = "PD0", "PD1", "PD2", "PD3", "PD4", "PD5", "PD8", "PD9", "PD6", "PD7",
"PD10", "PD11", "PD12", "PD13", "PD14", "PD15", "PD18", "PD19", "PD16", "PD17";
allwinner,function = "lvds1";
allwinner,muxsel = <3>;
allwinner,drive = <3>;
allwinner,pull = <0>;
};

    lvds2link_pins_b: lvds2link@1 {
            allwinner,pins = "PD0", "PD1", "PD2", "PD3", "PD4", "PD5", "PD8", "PD9", "PD6", "PD7", \
                    "PD10", "PD11", "PD12", "PD13", "PD14", "PD15", "PD18", "PD19", "PD16", "PD17";
            allwinner,pname = "PD0", "PD1", "PD2", "PD3", "PD4", "PD5", "PD8", "PD9", "PD6", "PD7", \
                    "PD10", "PD11", "PD12", "PD13", "PD14", "PD15", "PD18", "PD19", "PD16", "PD17";
            allwinner,function = "lvds1_suspend";
            allwinner,muxsel = <7>;
            allwinner,drive = <3>;
            allwinner,pull = <0>;
    };

但是仍然报错，请问这是为什么呢？我需要如何去做才能调通这个屏幕呢？
