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";
};
