[yocto] Display 1920x1080 double LVDS channel problem

[Enrico Bonomi]

Hi,

I'm working with an imx6duallite with Yocto 1.7.3. I want to drive a
1920x1080 display with 2 LVDS channels but i came across a problem.
Pictures are shown correctly on display but they have wrong colors (for
example a blue bar during psplash is shown pink).

my .dts has the following ldb:

&ldb {
ipu_id = <1>;
disp_id = <0>;
ext_ref = <1>;
mode = "sep0";
sec_ipu_id = <1>;
sec_disp_id = <1>;
status = "okay";
split-mode;

lvds-channel at 0{
fsl,data-mapping = "spwg";
fsl,data-width = <24>;
crtc = "ipu1-di0";
status = "okay";
};

lvds-channel at 1{
fsl,data-mapping = "spwg";
fsl,data-width = <24>;
crtc = "ipu1-di0";
status = "okay";
};
