Freescale i.MX7 CMOS Sensor Interface
|
||
|
|
=====================================
|
||
|
|
|
||
|
|
csi node
|
||
|
|
--------
|
||
|
|
|
||
|
|
This is device node for the CMOS Sensor Interface (CSI) which enables the chip
|
||
|
|
to connect directly to external CMOS image sensors.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
|
||
|
|
- compatible : "fsl,imx7-csi";
|
||
|
|
- reg : base address and length of the register set for the device;
|
||
|
|
- interrupts : should contain CSI interrupt;
|
||
|
|
- clocks : list of clock specifiers, see
|
||
|
|
Documentation/devicetree/bindings/clock/clock-bindings.txt for details;
|
||
|
|
- clock-names : must contain "axi", "mclk" and "dcic" entries, matching
|
||
|
|
entries in the clock property;
|
||
|
|
|
||
|
|
The device node shall contain one 'port' child node with one child 'endpoint'
|
||
|
|
node, according to the bindings defined in:
|
||
|
|
Documentation/devicetree/bindings/media/video-interfaces.txt.
|
||
|
|
|
||
|
|
In the following example a remote endpoint is a video multiplexer.
|
||
|
|
|
||
|
|
example:
|
||
|
|
|
||
|
|
csi: csi@30710000 {
|
||
|
|
#address-cells = <1>;
|
||
|
|
#size-cells = <0>;
|
||
|
|
|
||
|
|
compatible = "fsl,imx7-csi";
|
||
|
|
reg = <0x30710000 0x10000>;
|
||
|
|
interrupts = <GIC_SPI 7 IRQ_TYPE_LEVEL_HIGH>;
|
||
|
|
clocks = <&clks IMX7D_CLK_DUMMY>,
|
||
|
|
<&clks IMX7D_CSI_MCLK_ROOT_CLK>,
|
||
|
|
<&clks IMX7D_CLK_DUMMY>;
|
||
|
|
clock-names = "axi", "mclk", "dcic";
|
||
|
|
|
||
|
|
port {
|
||
|
|
csi_from_csi_mux: endpoint {
|
||
|
|
remote-endpoint = <&csi_mux_to_csi>;
|
||
|
|
};
|
||
|
|
};
|
||
|
|
};
