Subject: [PATCH] mtd: ofpart: add of_match_table with "fixed-partitions"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This allows using this parser with any flash driver that takes care of
setting of_node (using mtd_set_of_node helper) correctly. Up to now
support for "fixed-partitions" DT compatibility string was working only
with flash drivers that were specifying "ofpart" (manually or by letting
mtd use the default set of parsers).
This matches existing bindings documentation.
