DART-6UL/VAR-SOM-MX7- Display

Introduction

The i.MX6UL & i.MX7 have an RGB controller. We added SN75LVDS83B RGB to LVDS bridge on our custom boards.
So, you can use either an LVDS or RGB display.

Configuring your display in the Device Tree

To add support for your own display, edit the following section in the Device Tree.
You can use the instructions on the "Build the Linux kernel from source code" Wiki section, to compile the Device Tree.

&lcdif {
	pinctrl-names = "default";
	pinctrl-0 = <&pinctrl_lcdif_dat
		     &pinctrl_lcdif_ctrl>;
	display = <&display0>;
	status = "okay";

        display0: display0 {
		bits-per-pixel = <32>;
		bus-width = <24>;

	        display-timings {
			native-mode = <&timingr0>;
			timingr0: hsd100pxn1 {
				clock-frequency = <29232000>;
				hactive = <800>;
				vactive = <480>;
				hfront-porch = <40>;
				hback-porch = <40>;
				vsync-len = <48>;
				vback-porch = <29>;
				vfront-porch = <13>;
				hsync-len = <3>;
				hsync-active = <0>;
				vsync-active = <0>;
				de-active = <1>;
				pixelclk-active = <0>;
			};
		};
	};
};
