    7 title: Partition
    8 
    9 description: |
   10   This binding describes a single flash partition. Each partition must have its
   11   relative offset and size specified. Depending on partition function extra
   12   properties can be used.
   13 
   14   A partition may be dynamically allocated by a specific parser at runtime.
   15   In this specific case, a specific suffix is required to the node name.
   16   Everything after 'partition-' will be used as the partition name to compare
   17   with the one dynamically allocated by the specific parser.
   18   If the partition contains invalid char a label can be provided that will
   19   be used instead of the node name to make the comparison.
   20   This is used to assign an OF node to the dynamiccally allocated partition
   21   so that subsystem like NVMEM can provide an OF node and declare NVMEM cells.
   22   The OF node will be assigned only if the partition label declared match the
   23   one assigned by the parser at runtime.
