Please read more carefully my last comment: https://lore.kernel.org/lkml/20220704131810.kabkuy6e4qmhfm3n@mobilestation/ The definition is supposed to look like this: > + - if: > + properties: > + compatible: > + contains: > + const: amd,pensando-elba-spi > + then: + properties: + amd,pensando-elba-syscon + $ref: /schemas/types.yaml#/definitions/phandle + description: AMD Pensando Elba SoC system controller > + required: > + - amd,pensando-elba-syscon * Please also note that I've replaced "enum:" with "const:" in the if statement above. The difference with what you suggested is that my version is applicable for the Pensando ELBA SPI controller only, while your update will cause applying the "amd,pensando-elba-syscon" property constraints for all DW SSI controllers which isn't what we would want. -Sergey > patternProperties: > "^.*@[0-9a-f]+$": > type: object > > Regards, > Brad
