* Freescale MXS LCD Interface (LCDIF)

Required properties:
- compatible: Should be "fsl,<chip>-lcdif".  Supported chips include
  imx23 and imx28.
- reg: Address and length of the register set for lcdif
- interrupts: Should contain lcdif interrupts
- display : phandle to display node (see below for details)

* display node

Required properties:
- bits-per-pixel : <16> for RGB565, <32> for RGB888/666.
- bus-width : number of data lines.  Could be <8>, <16>, <18> or <24>.

Required sub-node:
- display-timings : Refer to binding doc display-timing.txt for details.

Examples:

lcdif@80030000 {
	compatible = "fsl,imx28-lcdif";
	reg = <0x80030000 2000>;
	interrupts = <38 86>;

	display: display {
		bits-per-pixel = <32>;
		bus-width = <24>;

		display-timings {
			native-mode = <&timing0>;
			timing0: timing0 {
				clock-frequency = <33500000>;
				hactive = <800>;
				vactive = <480>;
				hfront-porch = <164>;
				hback-porch = <89>;
				hsync-len = <10>;
				vback-porch = <23>;
				vfront-porch = <10>;
				vsync-len = <10>;
				hsync-active = <0>;
				vsync-active = <0>;
				de-active = <1>;
				pixelclk-active = <0>;
			};
		};
	};
