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 */
|
|
};
|
|
};

};
