   1 Atmel Image Sensor Interface (ISI) SoC Camera Subsystem
   2 ----------------------------------------------
   3
   4 Required properties:
   5 - compatible: must be "atmel,at91sam9g45-isi"
   6 - reg: physical base address and length of the registers set for the device;
   7 - interrupts: should contain IRQ line for the ISI;
   8 - clocks: list of clock specifiers, corresponding to entries in
   9           the clock-names property;
  10 - clock-names: must contain "isi_clk", which is the isi peripherial clock.
  11
  12 ISI supports a single port node with parallel bus. It should contain one
  13 'port' child node with child 'endpoint' node. Please refer to the bindings
  14 defined in Documentation/devicetree/bindings/media/video-interfaces.txt.
