Instead of listing directly properties typical for SPI peripherals, reference the spi-peripheral-props.yaml schema. This allows using all properties typical for SPI-connected devices, even these which device bindings author did not tried yet. Remove the spi-* properties which now come via spi-peripheral-props.yaml schema, except for the cases when device schema adds some constraints like maximum frequency. While changing additionalProperties->unevaluatedProperties, put it in typical place, just before example DTS.a The binding references also input.yaml and lists explicitly allowed properties, thus here reference only spi-peripheral-props.yaml for purpose of documenting the SPI slave device and bringing spi-max-frequency type validation. Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx> --- Technically, this depends on [1] merged to SPI tree, if we want to preserve existing behavior of not allowing SPI CPHA and CPOL in each of schemas in this patch. If this patch comes independently via different tree, the SPI CPHA and CPOL will be allowed for brief period of time, before [1] is merged. This will not have negative impact, just DT schema checks will be loosened for that period.
