   1 Freescale imx21 Framebuffer
   2
   3 This framebuffer driver supports devices imx1, imx21, imx25, and imx27.
   4
   5 Required 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
  10 Required 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
  17 Optional 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.
