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.

V2: - Merge the new bindings into mxsfb.txt file instead of keeping
them in separate mxsfb-drm.txt file.
- Add dedicated compatible for i.MX6SX
- Drop all references to DRM/KMS
- Repair the required bits in clock node

* 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.
+ Should be "fsl,imx6sx-lcdif" for i.MX6SX.
+- reg: Address and length of the register set for lcdif
+- interrupts: Should contain lcdif interrupts
+- 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 MXSFB block clock
+ - (MX6SX-only) "axi", "disp_axi" for the bus interface clock
+
+Required sub-nodes:
+ - port: The connection to an encoder chip.
+
+Example:
+
+ lcdif1: lcdif@02220000 {
+ 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>;
+ };
+ };
+ };
+
+Old bindings:
+=============
Required properties:
- compatible: Should be "fsl,imx23-lcdif" for i.MX23.
Should be "fsl,imx28-lcdif" for i.MX28.
