| 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: A port node with endpoint definitions as defined in |
| Documentation/devicetree/bindings/media/video-interfaces.txt. |
| |
| example: |
| |
| display@di0 { |
| compatible = "fsl,imx-parallel-display"; |
| edid = [edid-data]; |
| interface-pix-fmt = "rgb24"; |
| |
| port { |
| display_in: endpoint { |
| remote-endpoint = <&ipu_di0_disp0>; |
| }; |
| }; |
| }; |
