Adding property amd,pensando-elba-syscon was a result of this thread: https://lore.kernel.org/lkml/20220621101159.stvan53rvr6qugna@mobilestation/ >Define properties in top level "properties:" and here only allow (: >true) or disallow (: false) them.

The code should tell what the property does, what is its purpose, how it is used etc. Your property description basically copies the name without giving any new information. Best regards, Krzysztof

Yes, I looked past the description, thanks. See below the updated description and added amd,pensando-elba-syscon definition to top level properties. The property is added to the end as I see partial alphabetical ordering. --- a/Documentation/devicetree/bindings/spi/snps,dw-apb-ssi.yaml +++ b/Documentation/devicetree/bindings/spi/snps,dw-apb-ssi.yaml @@ -37,6 +37,17 @@ allOf: else: required: - interrupts + - if: + properties: + compatible: + contains: + const: amd,pensando-elba-spi + then: + required: + - amd,pensando-elba-syscon + else: + properties: + amd,pensando-elba-syscon: false properties: compatible: @@ -63,6 +74,8 @@ properties: const: intel,keembay-ssi - description: Intel Thunder Bay SPI Controller const: intel,thunderbay-ssi + - description: AMD Pensando Elba SoC SPI Controller + const: amd,pensando-elba-spi - description: Baikal-T1 SPI Controller const: baikal,bt1-ssi - description: Baikal-T1 System Boot SPI Controller @@ -136,6 +149,12 @@ properties: of the designware controller, and the upper limit is also subject to controller configuration. + amd,pensando-elba-syscon: + $ref: /schemas/types.yaml#/definitions/phandle-array + description: | + Block address to control four spi chip-selects.
