   4 Subject: [PATCH] mtd: bcm47xxpart: add of_match_table with a new DT binding
   5 MIME-Version: 1.0
   6 Content-Type: text/plain; charset=UTF-8
   7 Content-Transfer-Encoding: 8bit

   9 This allows using bcm47xxpart parser to find partitions on flash
  10 described in DT using the "brcm,bcm947xx-cfe-partitions" compatible
  11 property. It means this parser doesn't have to be explicitly selected by
  12 a flash driver anymore. It can be used e.g. together with a generic
  13 m25p80 / spi-nor if device is just properly described.
