When using LVDS LCD in 6-bit mode

Hi All,

Tell me how to control the LVDS port output.

We try to use a specific LVDS-LCD with i.MX6-Solo.

When the LCD is in 6-bit mode, according to the LCD spec, the RXIN3 +/- input level should be fixed.

What settings should I make for i.MX6?

How should I change the DeviceTree and Driver-Code?

Best Regards,

George.

Hi George

for such mode one can use ldb dts settings

fsl,data-mapping = "spwg";
fsl,data-width = <18>;

as in example below (&ldb {...)

adjust lcd timings as in example below

Best regards
