Dual Channel LVDS Display

Calculating Timings parameter of LVDS Panel SOP OS: Yocto 1.8 Modify imx6qdl-advantech.dtsi Step1: In ldb parameter, add parameter --> split-mode; /* dual-channel setting *

  &ldb {
       ext_ref = "true";
       status = "okay";
       split-mode; /* dual-channel setting */

Step2: In lvds-channel@1, change [crtc = "ipu1-di1";] to [crtc = "ipu1-di0";]

       lvds-channel@1 {
               fsl,data-mapping = "spwg";
               fsl,data-width = <24>;
               /* crtc = "ipu1-di1"; */
               crtc = "ipu1-di0"; /* dual-channel setting */
               status = "okay";

Step3: In display-timings native-mode = <&timing0>, Delete the other panel parameter.Add" LTI370LN01 " Parameter

        //Dual channel panel
                       timing0: lti370ln01 {
                               clock-frequency = <148500000>;
                               hactive = <1920>;
                               vactive = <544>;
                               hback-porch = <70>;
                               hfront-porch = <70>;
                               vback-porch = <200>;
                               vfront-porch = <200>;
                               hsync-len = <140>;
                               vsync-len = <185>;
                       };

Calculating Timings parameter Check your panel Timing table Example : samsung 37 inch panel
