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

Browse Source 
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)
