   1Freescale imx21 Framebuffer
   2
   3This framebuffer driver supports devices imx1, imx21, imx25, and imx27.
   4
   5Required properties:
   6- compatible : "fsl,<chip>-fb", chip should be imx1 or imx21
   7- reg : Should contain 1 register ranges(address and length)
   8- interrupts : One interrupt of the fb dev
   9
  10Required nodes:
  11- display: Phandle to a display node as described in
  12        Documentation/devicetree/bindings/video/display-timing.txt
  13        Additional, the display node has to define properties:
  14        - bits-per-pixel: Bits per pixel
  15        - fsl,pcr: LCDC PCR value
  16
  17Optional properties:
  18- fsl,dmacr: DMA Control Register value. This is optional. By default, the
  19        register is not modified as recommended by the datasheet.
  20- fsl,lscr1: LCDC Sharp Configuration Register value.
  21
  22Example:
  23
  24        imxfb: fb@10021000 {
  25                compatible = "fsl,imx21-fb";

  27                reg = <0x10021000 0x1000>;
  28                display = <&display0>;
