+DT bindings for the LCD2S Character LCD Display
+
+The LCD2S is a Character LCD Display manufactured by Modtronix Engineering.
+The display supports a serial I2C and SPI interface. The driver currently
+only supports the I2C interface.
+
+Required properties:
+ - compatible: Must contain "modtronix,lcd2s",
+ - 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>;
+ };
+};
