This backports upstream support for "compatible" DT property set for the "partitions" subnode of flash node. It allows specifying how partitions should be created/parsed. Right now only "fixed-partitions" is supported. It should eventually replace our downstream "linux,part-probe" solution. Signed-off-by: Rafał Miłecki <rafal@milecki.pl>

Subject: [PATCH] mtd: ofpart: add of_match_table with "fixed-partitions"

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.
