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 at 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.
