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" or "fsl,imx6ul-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 "mclk";
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_CSI_MCLK_ROOT_CLK>;
clock-names = "mclk";
port {
csi_from_csi_mux: endpoint {
remote-endpoint = <&csi_mux_to_csi>;
};
};
};
