Documentation/devicetree/bindings/resource-names.txt

   1 Some properties contain an ordered list of 1 or more datum which are
   2 normally accessed by index.  However, some devices will have multiple
   3 values which are more naturally accessed by name.  Device nodes can
   4 include a supplemental property for assigning names to each of the list
   5 items.  The names property consists of a list of strings in the same
   6 order as the data in the resource property.
   7
   8 The following supplemental names properties are defined.
   9
  10 Resource Property       Supplemental Names Property
  11 -----------------       ---------------------------
  12 reg                     reg-names
  13 clocks                  clock-names
  14 interrupts              interrupt-names
  15
  16 Usage:
  17
  18 The -names property must be used in conjunction with the normal resource
  19 property. If not it will be ignored.
