This is a quite large renaming to consolidate display related bindings into a single "display" directory from various scattered locations of video, drm, gpu, fb, mipi, and panel. The prior location was somewhat based on the Linux driver location, but bindings should be independent of that.

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>;
|
|
};
|
|
};
|
|
};
