|
drive DVI monitors.
|
|
|
|
Required properties:
|
|
- compatible : should be "smi,sm501".
|
|
- reg : contain two entries:
|
|
- First entry: System Configuration register
|
|
- Second entry: IO space (Display Controller register)
|
|
- interrupts : SMI interrupt to the cpu should be described here.
|
|
|
|
Optional properties:
|
|
- mode : select a video mode:
|
|
<xres>x<yres>[-<bpp>][@<refresh>]
|
|

display@1,0 {
|
|
compatible = "smi,sm501";
|
|
reg = <1 0x00000000 0x00800000
|
|
1 0x03e00000 0x00200000>;
|
|
interrupts = <1 1 3>;
|
|
mode = "640x480-32@60";
|
|
edid = [edid-data];
