Allwinner V3s Camera Sensor Interface

-------------------------------------



Allwinner V3s SoC features a CSI module(CSI1) with parallel interface.



Required properties:

  - compatible: value must be "allwinner,sun8i-v3s-csi"

  - reg: base address and size of the memory-mapped region.

  - interrupts: interrupt associated to this IP

  - clocks: phandles to the clocks feeding the CSI

    * bus: the CSI interface clock

    * mod: the CSI module clock

    * ram: the CSI DRAM clock

  - clock-names: the clock names mentioned above

  - resets: phandles to the reset line driving the CSI



The CSI node should contain one 'port' child node with one child 'endpoint'

node, according to the bindings defined in

Documentation/devicetree/bindings/media/video-interfaces.txt.



Endpoint node properties for CSI

---------------------------------

See the video-interfaces.txt for a detailed description of these properties.

- remote-endpoint	: (required) a phandle to the bus receiver's endpoint

			   node

- bus-width:		: (required) must be 8, 10, 12 or 16

- pclk-sample		: (optional) (default: sample on falling edge)

- hsync-active		: (required; parallel-only)

- vsync-active		: (required; parallel-only)



Example:



csi1: csi@1cb4000 {

	compatible = "allwinner,sun8i-v3s-csi";

	reg = <0x01cb4000 0x1000>;

	interrupts = <GIC_SPI 84 IRQ_TYPE_LEVEL_HIGH>;

	clocks = <&ccu CLK_BUS_CSI>,

		 <&ccu CLK_CSI1_SCLK>,

		 <&ccu CLK_DRAM_CSI>;

	clock-names = "bus", "mod", "ram";

	resets = <&ccu RST_BUS_CSI>;



	port {

		/* Parallel bus endpoint */

		csi1_ep: endpoint {

			remote-endpoint = <&adv7611_ep>;

			bus-width = <16>;



			/* If hsync-active/vsync-active are missing,

			   embedded BT.656 sync is used */

			hsync-active = <0>; /* Active low */

			vsync-active = <0>; /* Active low */

			pclk-sample = <1>;  /* Rising */

		};

	};

};
