Binding for ASCII LCD displays on Imagination Technologies boardsRequired properties:- compatible : should be one of: "img,boston-lcd" "mti,malta-lcd" "mti,sead3-lcd"Required properties for "img,boston-lcd":- reg : memory region locating the device registersRequired properties for "mti,malta-lcd" or "mti,sead3-lcd":- regmap: phandle of the system controller containing the LCD registers- offset: offset in bytes to the LCD registers within the system controllerThe layout of the registers & properties of the display are determinedfrom the compatible string, making this binding somewhat trivial.
