   9 This allows using this parser with any flash driver that takes care of
  10 setting of_node (using mtd_set_of_node helper) correctly. Up to now
  11 support for "fixed-partitions" DT compatibility string was working only
  12 with flash drivers that were specifying "ofpart" (manually or by letting
  13 mtd use the default set of parsers).

  15 This matches existing bindings documentation.
