imx6qdl-sabresd.dtsi中lvds接口显示配置如下：

&ldb {
status = "okay";

lvds-channel@0 {
  fsl,data-mapping = "spwg";
  fsl,data-width = <18>;
  primary;
  ipu_id = <1>;
  disp_id = <0>;
  status = "okay";

  display-timings {
   native-mode = <&timing0>;
   timing0: hsd100pxn1 {
    clock-frequency = <65000000>;
    hactive = <1024>;
    vactive = <768>;
    hback-porch = <220>;
    hfront-porch = <40>;
    vback-porch = <21>;
    vfront-porch = <7>;
    hsync-len = <60>;
    vsync-len = <10>;
   };
  };
};

lvds-channel@1 {
  fsl,data-mapping = "spwg";
  fsl,data-width = <18>;
/* primary; */
  status = "okay";

  display-timings {
   native-mode = <&timing1>;
   timing1: hsd100pxn1 {
    clock-frequency = <65000000>;
    hactive = <1024>;
    vactive = <768>;
    hback-porch = <220>;
    hfront-porch = <40>;
    vback-porch = <21>;
    vfront-porch = <7>;
    hsync-len = <60>;
    vsync-len = <10>;
   };
  };
