+  - reg: I2C bus address of the display,
+  - display-height-chars: Height of the display, in character cells,
+  - display-width-chars: Width of the display, in character cells.
+
+Example:

+i2c1: i2c@0 {
+	compatible = "ti,omap3-i2c";
+
+	lcd2s: auxdisplay@28 {
+		reg = <0x28>;
+		compatible = "modtronix,lcd2s";
+		display-height-chars = <4>;
+		display-width-chars = <20>;
+	};
