   1 Freescale i.MX7 CMOS Sensor Interface
   2 =====================================
   3
   4 csi node
   5 --------
   6
   7 This is device node for the CMOS Sensor Interface (CSI) which enables the chip
   8 to connect directly to external CMOS image sensors.
   9
  10 Required properties:
  11
  12 - compatible    : "fsl,imx7-csi";
  13 - reg           : base address and length of the register set for the device;
  14 - interrupts    : should contain CSI interrupt;
  15 - clocks        : list of clock specifiers, see
  16         Documentation/devicetree/bindings/clock/clock-bindings.txt for details;
  17 - clock-names   : must contain "axi", "mclk" and "dcic" entries, matching
  18                  entries in the clock property;
  19
  20 The device node shall contain one 'port' child node with one child 'endpoint'
  21 node, according to the bindings defined in:
  22 Documentation/devicetree/bindings/media/video-interfaces.txt.
  23
  24 In the following example a remote endpoint is a video multiplexer.

  26 example:
  27
  28                 csi: csi@30710000 {
  29                         #address-cells = <1>;
  30                         #size-cells = <0>;
  31
  32                         compatible = "fsl,imx7-csi";
  33                         reg = <0x30710000 0x10000>;
  34                         interrupts = <GIC_SPI 7 IRQ_TYPE_LEVEL_HIGH>;
  35                         clocks = <&clks IMX7D_CLK_DUMMY>,
  36                                         <&clks IMX7D_CSI_MCLK_ROOT_CLK>,
  37                                         <&clks IMX7D_CLK_DUMMY>;
  38                         clock-names = "axi", "mclk", "dcic";
  39
  40                         port {
  41                                 csi_from_csi_mux: endpoint {
  42                                         remote-endpoint = <&csi_mux_to_csi>;
  43                                 };
  44                         };
  45                 };
