+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>;
+ };
+ };
+ };
