Binding for ASCII LCD displays on Imagination Technologies boards



Required 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 registers



Required 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 controller



The layout of the registers & properties of the display are determined

from the compatible string, making this binding somewhat trivial.
