Freescale i.MX DRM master device
================================
The freescale i.MX DRM master device is a virtual device needed to list all
IPU or other display interface nodes that comprise the graphics subsystem.
Required properties:
- compatible: Should be "fsl,imx-display-subsystem"
- ports: Should contain a list of phandles pointing to display interface ports
of IPU devices
example:
display-subsystem {
compatible = "fsl,display-subsystem";
ports = <&ipu_di0>;
};
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.
- resets: phandle pointing to the system reset controller and
reset line index, see reset/fsl,imx-src.txt for details
Optional properties:
- port@[0-3]: Port nodes with endpoint definitions as defined in
Documentation/devicetree/bindings/media/video-interfaces.txt.
Ports 0 and 1 should correspond to CSI0 and CSI1,
ports 2 and 3 should correspond to DI0 and DI1, respectively.
example:
ipu: ipu@18000000 {
#address-cells = <1>;
#size-cells = <0>;
compatible = "fsl,imx53-ipu";
reg = <0x18000000 0x080000000>;
interrupts = <11 10>;
resets = <&src 2>;
ipu_di0: port@2 {
reg = <2>;
ipu_di0_disp0: endpoint {
remote-endpoint = <&display_in>;
};
};
};
Parallel display support
========================
Required properties:
- compatible: Should be "fsl,imx-parallel-display"
Optional properties:
- interface_pix_fmt: How this display is connected to the
display interface. Currently supported types: "rgb24", "rgb565", "bgr666"
and "lvds666".
- edid: verbatim EDID data block describing attached display.
- ddc: phandle describing the i2c bus handling the display data
channel
- port@[0-1]: Port nodes with endpoint definitions as defined in
Documentation/devicetree/bindings/media/video-interfaces.txt.
Port 0 is the input port connected to the IPU display interface,
port 1 is the output port connected to a panel.
example:
display@di0 {
compatible = "fsl,imx-parallel-display";
edid = [edid-data];
interface-pix-fmt = "rgb24";
port@0 {
reg = <0>;
display_in: endpoint {
remote-endpoint = <&ipu_di0_disp0>;
};
};
port@1 {
reg = <1>;
display_out: endpoint {
remote-endpoint = <&panel_in>;
};
};
};
panel {
...
port {
panel_in: endpoint {
remote-endpoint = <&display_out>;
};
};
};
