| Marvell MMP2 camera host interface |
| |
| Required properties: |
| - compatible: Should be "marvell,mmp2-ccic". |
| - reg: Register base and size. |
| - interrupts: The interrupt number. |
| - #clock-cells: Must be 0. |
| |
| Optional properties: |
| - clocks: Reference to the input clock as specified by |
| Documentation/devicetree/bindings/clock/clock-bindings.txt. |
| - clock-names: Names of the clocks used; "axi" for the AXI bus interface, |
| "func" for the peripheral clock and "phy" for the parallel |
| video bus interface. |
| - clock-output-names: Optional clock source for sensors. Shall be "mclk". |
| |
| Required subnodes: |
| - port: The parallel bus interface port with a single endpoint linked to |
| the sensor's endpoint as described in |
| Documentation/devicetree/bindings/media/video-interfaces.txt. |
| |
| Required endpoint properties: |
| - bus-type: data bus type, <5> or <6> for Parallel or Bt.656 respectively |
| - pclk-sample: pixel clock polarity |
| - hsync-active: horizontal synchronization polarity (only required for |
| parallel bus) |
| - vsync-active: vertical synchronization polarity (only required for |
| parallel bus) |
| |
| Example: |
| |
| camera0: camera@d420a000 { |
| compatible = "marvell,mmp2-ccic"; |
| reg = <0xd420a000 0x800>; |
| interrupts = <42>; |
| clocks = <&soc_clocks MMP2_CLK_CCIC0>; |
| clock-names = "axi"; |
| #clock-cells = <0>; |
| clock-output-names = "mclk"; |
| |
| port { |
| camera0_0: endpoint { |
| remote-endpoint = <&ov7670_0>; |
| bus-type = <5>; /* Parallel */ |
| hsync-active = <1>; /* Active high */ |
| vsync-active = <1>; /* Active high */ |
| pclk-sample = <0>; /* Falling */ |
| }; |
| }; |
