The mtd support for the nvmem api has been stalled from 2018 with a patch
half pushed hoping that a scheme is found for the mtd name later. This
patchset try to address this.
The solution is simple.
New partitions scheme should always have the partitions {} structure and
declare subnodes as partitions is deprecated and should not be used anymore.
Fixed-partitions parser is changed to parse direct subnode as partitions
only if the appropriate compatible is used. This change make possible
the use of nvmem-partitions compatible and the entire partition node can
be parsed by the nvmem of framework.
The current code register the partition to the nvmem framework every time
but skip actually of_node parting. The new nvmem-partitions compatible is
used to enable of_node parsing on the desired partitions.

mtd: partitions: ofpart: skip subnodes parse with compatible
mtd: core: add nvmem-partitions compatible to parse mtd as nvmem cells
dt-bindings: mtd: Document use of nvmem-partitions compatible
