dt-bindings: mxsfb: Add new bindings for the MXSFB driver 



Add new DT bindings for new MXSFB driver that is using the
OF graph to parse the video output structure instead of
hard-coding the display properties into the MXSFB node.
The old MXSFB fbdev driver bindings are preserved in the
same file in the "Old bindings" section.

* Freescale MXS LCD Interface (LCDIF)



New bindings:

=============

Required properties:

- compatible:	Should be "fsl,imx23-lcdif" for i.MX23.

		Should be "fsl,imx28-lcdif" for i.MX28.

- reg:		Address and length of the register set for lcdif

- interrupts:	Should contain lcdif interrupts

		Should be "fsl,imx6sx-lcdif" for i.MX6SX.

- reg:		Address and length of the register set for LCDIF

- interrupts:	Should contain LCDIF interrupt

- clocks:	A list of phandle + clock-specifier pairs, one for each

		entry in 'clock-names'.

- clock-names:	A list of clock names. For MXSFB it should contain:

    - "pix" for the LCDIF block clock

    - (MX6SX-only) "axi", "disp_axi" for the bus interface clock



Required sub-nodes:

  - port: The connection to an encoder chip.



Example:



	lcdif1: display-controller@2220000 {

		compatible = "fsl,imx6sx-lcdif", "fsl,imx28-lcdif";

		reg = <0x02220000 0x4000>;

		interrupts = <GIC_SPI 5 IRQ_TYPE_LEVEL_HIGH>;

		clocks = <&clks IMX6SX_CLK_LCDIF1_PIX>,

			 <&clks IMX6SX_CLK_LCDIF_APB>,

			 <&clks IMX6SX_CLK_DISPLAY_AXI>;

		clock-names = "pix", "axi", "disp_axi";



		port {

			parallel_out: endpoint {

				remote-endpoint = <&panel_in_parallel>;

			};

		};

	};



Deprecated bindings:

====================

Required properties:

- compatible:	Should be "fsl,imx23-lcdif" for i.MX23.

		Should be "fsl,imx28-lcdif" for i.MX28.

- reg:		Address and length of the register set for LCDIF

- interrupts:	Should contain LCDIF interrupts

- display:	phandle to display node (see below for details)
