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.

24 imxfb: fb@10021000 {
25 compatible = "fsl,imx21-fb";
26 interrupts = <61>;
27 reg = <0x10021000 0x1000>;
28 display = <&display0>;
29 };

35 native-mode = <&timing_disp0>;
36 bits-per-pixel = <16>;
37 fsl,pcr = <0xf0c88080>; /* non-standard but required */
