Hi Thomas

Documentation/devicetree/bindings/mtd/partition.txt:

The partition table should be a subnode of the mtd node and should be named
'partitions'. This node should have the following property:
- compatible : (required) must be "fixed-partitions"
Partitions are then defined in subnodes of the partitions node.

For backwards compatibility partitions as direct subnodes of the mtd device are
supported. This use is discouraged.

We should try to get this right when adding new DT nodes.
