We don't need them defined in both mtd and block. Could perhaps move them to bindings/partitions/, but that's not really worth it in my opinion. Just use and add to what's in mtd. > > diff --git a/Documentation/devicetree/bindings/block/partitions/partition.yaml b/Documentation/devicetree/bindings/block/partitions/partition.yaml > new file mode 100644 > index 000000000000..b9b1d8139e56 > --- /dev/null > +++ b/Documentation/devicetree/bindings/block/partitions/partition.yaml > @@ -0,0 +1,33 @@ > +# SPDX-License-Identifier: GPL-2.0-only OR BSD-2-Clause > +%YAML 1.2 > +--- > +$id: http://devicetree.org/schemas/block/partitions/partition.yaml# > +$schema: http://devicetree.org/meta-schemas/core.yaml# > + > +title: Partition > + > +description: | Don't need '|' if no formatting. > + This binding describes a single flash partition.

It's conceivable that some vendor invented their own scheme just like MTD devices. As I said before, this is just 'fixed-partitions'. If some properties aren't supported, that's fine. All the 'align' properties are for flashing tools and aren't supported in Linux. Rob

Generalize property from MTD partitions schema and introduce property for block partitions defined in OF. Partition schema for block devices is a reduced schema of the MTD as only a few property are supported for it.
