I also have the problem , i test with this device tree
with kernel 4.1
setenv addfb 'setenv bootargs ${bootargs} consoleblank=0 drm.debug=0xe console=tty0 ldb=spl0 video=LVDS-1:960x1080MR-32@50 video:LVDS-2::960x1080MR-32@50 fbmem=28M,28M'
timing still not correct but LCD show picture with line moving
&ldb {
split-mode;
status = "okay";
lvds-channel@0 {
fsl,data-mapping = "spwg";
fsl,data-width = <24>;
crtc = "ipu1-di0";
status = "okay";
display-timings {
native-mode = <&timing0>;
timing0: LQ156M3LW01 {
clock-frequency = <65000000>;
hactive = <960>;
vactive = <1080>;
hback-porch = <100>;
hfront-porch = <40>;
vback-porch = <30>;
vfront-porch = <3>;
hsync-len = <10>;
vsync-len = <2>;
};
};
};
lvds-channel@0 {
fsl,data-mapping = "spwg";
fsl,data-width = <24>;
crtc = "ipu1-di0";
status = "okay";
display-timings {
native-mode = <&timing1>;
timing1: LQ156M3LW01 {
clock-frequency = <65000000>;
hactive = <960>;
vactive = <1080>;
hback-porch = <100>;
hfront-porch = <40>;
vback-porch = <30>;
vfront-porch = <3>;
hsync-len = <10>;

};
};
};
