   2 ----------------------------------------------
   3
   4 Required properties for ISC:
   5 - compatible
   6         Must be "atmel,sama5d2-isc".
   7 - reg
   8         Physical base address and length of the registers set for the device.
   9 - interrupts
  10         Should contain IRQ line for the ISC.
  11 - clocks
  12         List of clock specifiers, corresponding to entries in
  13         the clock-names property;
  14         Please refer to clock-bindings.txt.
  15 - clock-names
  16         Required elements: "hclock", "iscck", "gck".
  17 - #clock-cells
  18         Should be 0.
  19 - clock-output-names
  20         Should be "isc-mck".
  21 - pinctrl-names, pinctrl-0
  22         Please refer to pinctrl-bindings.txt.
  23
  24 ISC supports a single port node with parallel bus. It should contain one
  25 'port' child node with child 'endpoint' node. Please refer to the bindings
  26 defined in Documentation/devicetree/bindings/media/video-interfaces.txt.
