   .Description
  -The compatible property value consists of one or more strings that define the specific
  -programming model for the device. This list of strings should be used by a client program for
  -device driver selection. The property value consists of a concatenated list of null terminated
  -strings, from most specific to most general. They allow a device to express its compatibility
  -with a family of similar devices, potentially allowing a single device driver to match against
  -several devices.

   The recommended format is “manufacturer,model”, where manufacturer is a
  -string describing the name of the manufacturer (such as a stock ticker symbol), and model
  -specifies the model number.

   .Example
   [listing]
   compatible = “fsl,mpc8641-uart”, “ns16550";
   
  -In this example, an operating system would first try to locate a device driver that supported
  -fsl,mpc8641-uart. If a driver was not found, it would then try to locate a driver that supported
  -the more general ns16550 device type.

positive.code: a phandle property with a unique <u32> value. That unique number is
  specified for the value of properties with a phandle value type.
  
  |<stringlist> a|A list of <string> values concatenated together. Example: The string list
  “hello”,“world” would be represented in memory as:
  [listing]
     address  68  'h'
   address+1  65  'e'
  
negative.code: interrupt tree reaches an interrupt controller node without an
  interrupts property and thus no explicit interrupt parent.
  
  See Figure 2-5 for an example of a graphical representation of a device
  tree with interrupt parent relationships shown. Figure 2-6 shows the
  corresponding interrupt tree.
