1Binding for ASCII LCD displays on Imagination Technologies boards
2
3Required properties:
4- compatible : should be one of:
5    "img,boston-lcd"
6    "mti,malta-lcd"
7    "mti,sead3-lcd"
8
9Required properties for "img,boston-lcd":
10- reg : memory region locating the device registers
11
12Required properties for "mti,malta-lcd" or "mti,sead3-lcd":
13- regmap: phandle of the system controller containing the LCD registers
14- offset: offset in bytes to the LCD registers within the system controller
15
16The layout of the registers & properties of the display are determined
17from the compatible string, making this binding somewhat trivial.
