* Solomon SSD1289 Framebuffer Driver
|
||||
|
||||
Required properties:
|
||||
- compatible: Should be "solomon,ssd1289fb". The only supported bus for
|
||||
now is lbc.
|
||||
- reg: Should contain address of the controller on the LBC bus. The detail
|
||||
was described in Documentation/devicetree/bindings/powerpc/fsl/lbc.txt
|
||||
|
||||
Examples:
|
||||
display@2,0 {
|
||||
compatible = "solomon,ssd1289fb";
|
||||
reg = <0x2 0x0000 0x0004>;
