[PATCH v2 1/3] mtd: partitions: ofpart: skip subnodes parse with compatible

From: Ansuel Smith
Date: Tue Feb 16 2021 - 16:27:45 EST


If a partitions structure is not used, parse direct subnodes as
fixed-partitions only if a compatible is not found or is of type
fixed-partition. A parser can be used directly on the subnode and
subnodes should not be parsed as fixed-partitions by default.
