I use Left / Right type dual port Lvds   (not Odd/Even)

Channel 1 and Channel 2 display the same screen

What's the problem?

Imx6-sabresd / android 6.0.1 // kernel 4.1.15  //Panel is LA123WF1

 

imx6qdl-sabresd.dtsi

mxcfb1: fb@0 {
compatible = "fsl,mxc_sdc_fb";
disp_dev = "ldb";
interface_pix_fmt = "BGR24";
default_bpp = <32>;
int_clk = <0>;
late_init = <0>;
status = "okay";

}

&ldb {
status = "okay";
split-mode;
lvds-channel@0 {
fsl,data-mapping = "spwg";
fsl,data-width = <24>;
primary;
status = "okay";

display-timings {
native-mode = <&timing0>;
timing0: hsd100pxn1 {
clock-frequency = <89400000>; 

hactive = <1920>;
vactive = <720>;
hback-porch = <16>;
hfront-porch = <16>;
vback-porch = <3>;
vfront-porch = <3>;
hsync-len = <32>;
vsync-len = <2>;
};
};
};

}

 

What am I to do?

Thanks for your response.

Hello SON,

     Attachment is a patch for dual-lvds application in dts, you can modify resolution and other parameters according to your LCD datasheet.

Best Regards,

Weidong
