The example provided here worked but there is indeed a warning with the axg-frddr variant.
I'm adding a 2nd example so it does not happen again.
If the difference is only in one property, no need. If the difference is in more properties - then could be. We do not keep examples for every trivial change, because the assumption is that submitter tests DTS as well.
- reset-names: true
minItems maxItems
Adding this causes troubles with the reset-names definitions in the 'if' clause. If I put min: 1, max: 2 and min: 2 in the 'then' clause I get:
Documentation/devicetree/bindings/sound/amlogic,axg-fifo.yaml: allOf:1:then:properties:reset-names: 'oneOf' conditional failed, one must be fixed: [{'const': 'arb'}, {'const': 'rst'}] is too long [{'const': 'arb'}, {'const': 'rst'}] is too short False schema does not allow 2 1 was expected hint: "minItems" is only needed if less than the "items" list length from schema $id: http://devicetree.org/meta-schemas/items.yaml#
Probably because rest of binding does not match. One way is like this:
https://elixir.bootlin.com/linux/v5.19-rc6/source/Documentation/devicetree/b...
The older devices just have the 'arb' reset. Newer devices have a 2nd reset line (called rst here)
If I just restrict the min and max, it would be valid for the older devices to have 'rst' only - but it is not valid.
How? Why would you define for old devices "rst" as one name if this is not correct?
With just 'true', it works as expected (throw errors if an incorrect name or number of names is passed). Min and Max comes from the items list.
Because the rest is not in recommended way. Once you implement it in recommended way, there will be no such...
Any suggestions ?
Implement rest of comments.
