+Freescale i.MX IPUv3
+====================
+
+Required properties:
+- compatible: Should be "fsl,<chip>-ipu"
+- reg: should be register base and length as documented in the
+  datasheet
+- interrupts: Should contain sync interrupt and error interrupt,
+  in this order.
+- #crtc-cells: 1, See below
+
+example:
+
+ipu: ipu@18000000 {
+	#crtc-cells =<1>;
+	compatible = "fsl,imx53-ipu";
+	reg =<0x18000000 0x080000000>;
+	interrupts =<11 10>;
+};
+
+Parallel display support
+========================
+
+Required properties:
+- compatible: Should be "fsl,imx-parallel-display"
+- crtc: the crtc this display is connected to, see below
+Optional properties:
+- interface_pix_fmt: How this display is connected to the
+  crtc. Currently supported types: "rgb24", "rgb565"
+- edid: verbatim EDID data block describing attached display.
+- ddc: phandle describing the i2c bus handling the display data
+  channel
+
+example:
+
+display@di0 {
+	compatible = "fsl,imx-parallel-display";
+	edid = [edid-data];
+	crtc =<&ipu 0>;
+	interface-pix-fmt = "rgb24";
+};

Do you have a working sample of [edid-data] for a parallel/LVDS/HDMI
display or know a good way to produce one?

Thanks in advance,


Eric
