[PATCH 00/12] Improve MTD bindings

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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
