I have attached the DTS file I am using. With this configuration, the LVDS interface is enabled successfully, and the clock modes in DRM appear to be correct, but I am not getting any response on the display.</P><P>I am using a separate module for backlight control, so I am using the default backlight configuration. However, when I use the imx8mp-evk-jdi-wuxga-lvds-panel.dtb file, the display works and shows the test pattern.
