DART-6UL- LVDS
LVDS boot arguments
Introduction
The i.MX6UL has an RGB controller. We added SN75LVDS83B RGB to LVDS bridge on the custom board.
Switching to LVDS as main display
Switching to LVDS display requires changing the display paramters in the device tree,
&lcdif {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_lcdif_dat
&pinctrl_lcdif_ctrl>;
display = <&display0>;
status = "okay";
display0: display {
bits-per-pixel = <16>;
bus-width = <24>;
display-timings {
native-mode = <&timingr0>;
timingr0: hsd100pxn1 {
clock-frequency = <35714000>;
hactive = <800>;
vactive = <480>;
hback-porch = <24>;
hfront-porch = <15>;
vback-porch = <13>;
vfront-porch = <20>;
hsync-len = <20>;
vsync-len = <13>;
};
};
};
};
