-ARM Versatile Character LCD
------------------------------------------------------
-This binding defines the character LCD interface found on ARM Versatile AB
-and PB reference platforms.
-
-Required properties:
-- compatible : "arm,versatile-clcd"
-- reg : Location and size of character LCD registers
-
-Optional properties:
-- interrupts - single interrupt for character LCD. The character LCD can
-  operate in polled mode without an interrupt.
-
-Example:
-       lcd@10008000 {
-               compatible = "arm,versatile-lcd";
-               reg = <0x10008000 0x1000>;
-       };
