-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@...0a000 {
- 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 */
- };
- };
- };
