Subject: [PATCH] mtd: bcm47xxpart: add of_match_table with a new DT binding |
MIME-Version: 1.0 |
Content-Type: text/plain; charset=UTF-8 |
Content-Transfer-Encoding: 8bit |
|
This allows using bcm47xxpart parser to find partitions on flash |
described in DT using the "brcm,bcm947xx-cfe-partitions" compatible |
property. It means this parser doesn't have to be explicitly selected by |
a flash driver anymore. It can be used e.g. together with a generic |
m25p80 / spi-nor if device is just properly described. |
