2024-05-08dt-bindings: Use full path to other schemasKrzysztof Kozlowski
When referencing other schema, it is preferred to use an absolute path (/schemas/....), which allows also an seamless move of particular schema out of Linux kernel to dtschema.

2024-02-05dt-bindings: mtd: avoid automatically select from mtd.yamlZhenhua Huang
The mtd binding is always $ref'ed by other bindings, default selector should be from other binding files which ref'ed it. Now, "$nodename" in mtd.yaml turns into a "select" automatically such that a few binding check issues reported because it conflicts with sram devices(eg, qcom,imem.yaml, rules in folder sram/*) To avoid the automatically created "select" in mtd.yaml, adding: select: false Suggested-by: Bjorn Andersson <quic_bjorande@quicinc.com> Fixes: 7bdc671822e9 ("dt-bindings: mtd: physmap: Reuse the generic definitions") Signed-off-by: Zhenhua Huang <quic_zhenhuah@quicinc.com> Reviewed-by: Bjorn Andersson <quic_bjorande@quicinc.com> Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> Link: https://lore.kernel.org/linux-mtd/1704885705-7486-1-git-send-email-quic_zhenhuah@quicinc.com
2023-10-21dt-bindings: nvmem: move deprecated cells binding to its own fileRafał Miłecki
Support for old NVMEM fixed cells was deprecated in favour of "fixed-layout". It's still part of the nvmem.yaml though and may be unknowingly used by new bindings added without much of analyze. To make it more difficult to accidentally support old syntax move its binding to separated file with "deprecated" in its name.

2023-06-22dt-bindings: mtd: Accept nand related node namesMiquel Raynal
There is no addition there, but the mtd.yaml file is so generic, it can be referenced by a wide variety of devices, including nand ones which already define the node name to "nand@<cs>". Right now it does not lead to any failure but when we will constrain more the schema, this will become a problem because we want the mtd-wide properties like label or partitions to be available for the callers.

2023-04-05dt-bindings: Add missing (unevaluated|additional)Properties on child node ↵Rob Herring
schemas Just as unevaluatedProperties or additionalProperties are required at the top level of schemas, they should (and will) also be required for child node schemas. That ensures only documented properties are present. Add unevaluatedProperties or additionalProperties as appropriate, and then add any missing properties flagged by the addition.

2022-11-17dt-bindings: mtd: partitions: Constrain the list of parsersMiquel Raynal
Parser compatibles cannot be used anywhere, and the list is limited. In order to constrain this list, enumerate them all under the top "partitions" subnode. New parsers will have to add their own compatible here as well.

The memory mapped MTD devices also share a lot with all the other MTD devices, so let's share the properties by referencing mtd.yaml. We can then drop mentioning the properties, to the cost of mentioning the possible "sram" node name prefix.

Over time the various ways to define MTD partitions has evolved. Most of the controllers support several different bindings. Let's define all possible choices in one file and mark the legacy ones deprecated. This way, we can just reference this file and avoid dupplicating these definitions.
