1*4882a593SmuzhiyunBinding for ASCII LCD displays on Imagination Technologies boards
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunRequired properties:
4*4882a593Smuzhiyun- compatible : should be one of:
5*4882a593Smuzhiyun    "img,boston-lcd"
6*4882a593Smuzhiyun    "mti,malta-lcd"
7*4882a593Smuzhiyun    "mti,sead3-lcd"
8*4882a593Smuzhiyun
9*4882a593SmuzhiyunRequired properties for "img,boston-lcd":
10*4882a593Smuzhiyun- reg : memory region locating the device registers
11*4882a593Smuzhiyun
12*4882a593SmuzhiyunRequired properties for "mti,malta-lcd" or "mti,sead3-lcd":
13*4882a593Smuzhiyun- regmap: phandle of the system controller containing the LCD registers
14*4882a593Smuzhiyun- offset: offset in bytes to the LCD registers within the system controller
15*4882a593Smuzhiyun
16*4882a593SmuzhiyunThe layout of the registers & properties of the display are determined
17*4882a593Smuzhiyunfrom the compatible string, making this binding somewhat trivial.
