-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>;
-                                };
-                        };
-                };
