2024-04-17spi: renesas,sh-msiof: Add r8a779h0 supportGeert Uytterhoeven
Document support for the Clock-Synchronized Serial Interface with FIFO (MSIOF) in the Renesas R-Car V4M (R8A779H0) SoC.

2023-03-20spi: renesas,sh-msiof: Miscellaneous improvementsGeert Uytterhoeven
Make "clocks" and "power-domains" required everywhere. Make "resets" required on R-Car Gen2 and newer (i.e. all but SH-Mobile). Update the example to match reality: - Use interrupt binding definitions instead of hardcoded numbers, - Convert to new-style CPG/MSSR bindings, - Add missing "power-domains" and "resets" properties.

2022-08-30spi: renesas,sh-msiof: Fix 'unevaluatedProperties' warningsLad Prabhakar
With 'unevaluatedProperties' support implemented, there's a number of warnings when running dtbs_check: arch/arm64/boot/dts/renesas/r8a77951-ulcb-kf.dtb: spi@e6e90000: Unevaluated properties are not allowed ('power-domains', 'resets' were unexpected) From schema: Documentation/devicetree/bindings/spi/renesas,sh-msiof.yaml The main problem is that SoC DTSI's include power-domains and resets property, whereas the renesas,sh-msiof.yaml has 'unevaluatedProperties: false'. So just add optional power-domains and resets properties.

Scalar properties shouldn't have array constraints (minItems, maxItems, items). These constraints can simply be dropped with any constraints under 'items' moved up a level.

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.

2020-05-14dt-bindings: Fix incorrect 'reg' property sizesRob Herring
The examples template is a 'simple-bus' with a size of 1 cell for had between 2 and 4 cells which really only errors on I2C or SPI type devices with a single cell. The easiest fix in most cases is to change the 'reg' property to for 1 cell address and size. In some cases with child devices having 2 cells, that doesn't make sense so a bus node is needed.

2020-05-03dt-bindings: Remove cases of 'allOf' containing a '$ref'Rob Herring
json-schema versions draft7 and earlier have a weird behavior in that any keywords combined with a '$ref' are ignored (silently). The correct form was to put a '$ref' under an 'allOf'. This behavior is now changed in the 2019-09 json-schema spec and '$ref' can be mixed with other keywords. The json-schema library doesn't yet support this, but the tooling now does a fixup for this and either way works. This has been a constant source of review comments, so let's change this treewide so everyone copies the simpler syntax. Scripted with ruamel.yaml with some manual fixups. Some minor whitespace changes from the script.
