Hi,all

   I'm using the imx6ul-evk board, The lcd could not work. The log is following:

 

21c8000.lcdif supply lcd not found, using dummy regulator

mxsfb 21c8000.lcdif: failed to find mxc display driver

mxsfb 21c8000.lcdif: initialized

 

my DT:

&lcdif {
   pinctrl-names = "default";
   pinctrl-0 = <&pinctrl_lcdif_dat
                     &pinctrl_lcdif_ctrl>;
   display = <&display0>;
   status = "okay";

   display0: display {
      bits-per-pixel = <32>;
      bus-width = <24>;

      display-timings {
         native-mode = <&timing0>;
         timing0: timing0 {
            clock-frequency = <65000000>;
            hactive = <1024>;
            vactive = <768>;
            hback-porch = <220>;
            hfront-porch = <40>;
            hsync-len = <48>;
            vback-porch = <21>;
            vfront-porch = <7>;
            vsync-len = <60>;

            hsync-active = <0>;
            vsync-active = <0>;
            de-active = <0>; // 1: DE mode
            pixelclk-active = <0>;
         };
      };

   };

};

 

Could any one help me to solve this issue?

Thanks
