* 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>;
};
