2021-06-21dt-bindings: Drop redundant minItems/maxItemsRob Herring
If a property has an 'items' list, then a 'minItems' or 'maxItems' with the same size as the list is redundant and can be dropped. Note that is DT schema specific behavior and not standard json-schema behavior. The tooling will fixup the final schema adding any unspecified minItems/maxItems. This condition is partially checked with the meta-schema already, but only if both 'minItems' and 'maxItems' are equal to the 'items' length. An improved meta-schema is pending.

2021-03-23dt-bindings: Clean-up undocumented compatible stringsRob Herring
Adding checks for undocumented compatible strings reveals a bunch of warnings in the DT binding examples. Fix the cases which are typos, just a mismatch between the schema and the example, or aren't documented at all. In a couple of cases, fixing the compatible revealed some schema errors which are fixed. There's a bunch of others remaining after this which have bindings, but those aren't converted to schema yet.

2020-10-07dt-bindings: Add missing 'unevaluatedProperties'Rob Herring
This doesn't yet do anything in the tools, but make it explicit so we can check either 'unevaluatedProperties' or 'additionalProperties' is present in schemas. 'unevaluatedProperties' is appropriate when including another schema (via '$ref') and all possible properties and/or child nodes are not explicitly listed in the schema with the '$ref'. This is in preparation to add a meta-schema to check for missing 'unevaluatedProperties' or 'additionalProperties'. This has been a constant source of review issues.

spi@13000: clock-names: Additional items are not allowed ('pclk' was unexpected) spi@13000: clock-names: ['core', 'pclk'] is too long spi@13000: clocks: [[2, 23], [2, 258]] is too long spi@15000: clock-names: Additional items are not allowed ('pclk' was unexpected) spi@15000: clock-names: ['core', 'pclk'] is too long spi@15000: clocks: [[2, 29], [2, 261]] is too long Conditional schema properties don't overwrite others. Instead of restrictions have to be validated. So general clock amount is 1-2 and depending on the actual device type limit the mount to 1 or 2.
