What are changes needed to have HDMI working with 1280x800 resolution on imx6

Android version : Android M

Kernel version : 3.14

Right now making modification 

compatible = "fsl,imx6dl-SBC_A62", "fsl,imx6dl";

mxcfb1: fb@0 {
compatible = "fsl,mxc_sdc_fb";
disp_dev = "hdmi";
interface_pix_fmt = "RGB24";
mode_str ="1920x1080M@60";

mode_str ="1280x800M@60";
default_bpp = <32>;
int_clk = <0>;
late_init = <0>;
status = "okay";

This is the only change I am making at the moment. Issue is that 3/10 times HDMI screen fails to turn on. Please let me know if I am missing any other changes

Hi Igor ,

Thank you for your reply. I have gone through the thread shared by you .

one of the points mentioned in the discussion was to update the 1280*800 timing parameters into mxc_edid.c and mxc_hdmi.c.

I have made changes in the mxc_edid.c file but i am not quite sure what changes are required in mxc_hdmi.c file

Any hint could help.

Regards ,

Dileep
