Hello,
During a yaml conversion review, Krzysztof opened the discussion about
the links and references made between the different files in the mtd
bindings. I figured out some minimal changes might be needed to properly
reference everything correctly and ensure we constrain as much as
possible the existing bindings. That is what I tried to do here.
The idea is:
* partition.yaml defines one MTD partition
* parsers/*.yaml define partition parsers (mainly compatibles)
* mtd.yaml contains the generic definition of any mtd device (nand,
spi-nand, spi-nor, nor, sram, etc), in particular, it defines the
various partition formats (legacy and current) and references
partition.yaml as well as a list of all the possible parsers within a
"partitions" node.
* nand-chip.yaml, jedec,spi-nor, mtd-physmap.yaml all describe real
instances of mtd device, each of them with a different underlying
technology, they reference mtd.yaml
* nand-controller.yaml has subnodes which reference nand-chip.yaml.
* Specific NAND controller bindings reference nand-controller.yaml.
I've tested with the following command and it worked okay:
$ make dt_binding_check -j10 DT_CHECKER_FLAG=-m DT_SCHEMA_FILES=mtd/
Comments welcome of course :-)
Cheers,
Miquèl
