   1 Freescale i.MX DRM master device
   2 ================================
   3
   4 The freescale i.MX DRM master device is a virtual device needed to list all
   5 IPU or other display interface nodes that comprise the graphics subsystem.
   6
   7 Required properties:
   8 - compatible: Should be "fsl,imx-display-subsystem"
   9 - ports: Should contain a list of phandles pointing to display interface ports
  10   of IPU devices
  11
  12 example:
  13
  14 display-subsystem {
  15         compatible = "fsl,display-subsystem";
  16         ports = <&ipu_di0>;
  17 };
  18
  19
  20 Freescale i.MX IPUv3
  21 ====================
  22
  23 Required properties:
  24 - compatible: Should be "fsl,<chip>-ipu"
  25 - reg: should be register base and length as documented in the
  26   datasheet
  27 - interrupts: Should contain sync interrupt and error interrupt,
  28   in this order.
  29 - resets: phandle pointing to the system reset controller and
  30           reset line index, see reset/fsl,imx-src.txt for details
  31 Optional properties:
  32 - port@[0-3]: Port nodes with endpoint definitions as defined in
  33   Documentation/devicetree/bindings/media/video-interfaces.txt.
  34   Ports 0 and 1 should correspond to CSI0 and CSI1,
  35   ports 2 and 3 should correspond to DI0 and DI1, respectively.
  36
  37 example:
  38
  39 ipu: ipu@18000000 {
  40         #address-cells = <1>;
  41         #size-cells = <0>;
  42         compatible = "fsl,imx53-ipu";
  43         reg = <0x18000000 0x080000000>;
  44         interrupts = <11 10>;
  45         resets = <&src 2>;
  46
  47         ipu_di0: port@2 {
  48                 reg = <2>;
  49
  50                 ipu_di0_disp0: endpoint {
  51                         remote-endpoint = <&display_in>;
  52                 };
  53         };
  54 };
  55
  56 Parallel display support
  57 ========================
  58
  59 Required properties:
  60 - compatible: Should be "fsl,imx-parallel-display"
  61 Optional properties:
  62 - interface_pix_fmt: How this display is connected to the
  63   display interface. Currently supported types: "rgb24", "rgb565", "bgr666"
  64   and "lvds666".
  65 - edid: verbatim EDID data block describing attached display.
  66 - ddc: phandle describing the i2c bus handling the display data
  67   channel
  68 - port@[0-1]: Port nodes with endpoint definitions as defined in
  69   Documentation/devicetree/bindings/media/video-interfaces.txt.
  70   Port 0 is the input port connected to the IPU display interface,
  71   port 1 is the output port connected to a panel.
  72
  73 example:
  74
  75 display@di0 {
  76         compatible = "fsl,imx-parallel-display";
  77         edid = [edid-data];
  78         interface-pix-fmt = "rgb24";
  79
  80         port@0 {
  81                 reg = <0>;
  82
  83                 display_in: endpoint {
  84                         remote-endpoint = <&ipu_di0_disp0>;
  85                 };
  86         };
  87
  88         port@1 {
  89                 reg = <1>;
  90
  91                 display_out: endpoint {
  92                         remote-endpoint = <&panel_in>;
  93                 };
  94         };
  95 };
  96
  97 panel {
  98         ...
  99
 100         port {
 101                 panel_in: endpoint {
 102                         remote-endpoint = <&display_out>;
 103                 };
 104         };
