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 */
|
||||||
|
};
|
||||||
|
};
|
||||||
|
};
