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 */
};
};
};
