* 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>;
