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.
