My comment at v2 was already saying this: "This does not match what you have in conditional, so just keep min and max Items here." and you have numerous examples in the code for this.

Just to be clear, is the diff below what you would expect to see when applying both patch 1 and 4 in succession, that is the reset properties are described "generically" and the conditional section only describes the order and values: diff --git a/Documentation/devicetree/bindings/pci/brcm,stb-pcie.yaml b/Documentation/devicetree/bindings/pci/brcm,stb-pcie.yaml index 11f8ea33240c..faab7291d722 100644 --- a/Documentation/devicetree/bindings/pci/brcm,stb-pcie.yaml +++ b/Documentation/devicetree/bindings/pci/brcm,stb-pcie.yaml @@ -95,6 +95,28 @@ properties: minItems: 1 maxItems: 3 + resets: + minItems: 1 + maxItems: 3 + oneOf: + - description: reset controller handling the PERST# signal + - description: phandle pointing to the RESCAL reset controller + - items: + - description: phandle pointing to the RESCAL reset controller + - description: reset for PCIe/CPU bus bridge + - description: reset for soft PCIe core reset + + reset-names: + minItems: 1 + maxItems: 3 + oneOf: + - const: perst + - const: rescal + - items: + - const: rescal + - const: bridge + - const: swinit + required: - compatible - reg @@ -118,8 +140,7 @@ allOf: then: properties: resets: - items: - - description: reset controller handling the PERST# signal + maxItems: 1 reset-names: items: @@ -136,8 +157,7 @@ allOf: then: properties: resets: - items: - - description: phandle pointing to the RESCAL reset controller + maxItems: 1 reset-names: items: @@ -146,6 +166,22 @@ allOf: required: - resets - reset-names + - if: + properties: + compatible: + contains: + const: brcm,bcm7712-pcie + then: + properties: + resets: + minItems: 3 + + reset-names: + minItems: 3 + + required: + - resets + - reset-names unevaluatedProperties: false Thanks! -- Florian

That why it is nice to ack each reviewers comment. If reviewers comments are somehow trickier, then such acks or further clarifications are even more useful. Did it happen for v3? No. Best regards, Krzysztof

I now think what you are looking for is the top-level description of something like resets: maxItems: 1 oneOf: - description: reset controller handling the PERST# signal - description: phandle pointing to the RESCAL reset controller reset-names: maxItems: 1 oneOf: - const: perst - const: rescal I left out minItems because imItems==maxItems=1 Before I was giving both of them as the "potential candidates list" that will be used further on, but this is not how Yaml should be used. Is the above in the right direction? Regards, Jim Quinlan Broadcom STB/CM > > Best regards, > Krzysztof >

"Phandle"? It cannot be anything else. Redundant. "Pointing to"? Redundant. "reset-controller"? Well, resets always point to reset controller. So what is the point of this description?

It's over complicated. First maxItems are redundant, because you define number of items in items. Second, you have EXACTLY the same case as the hardware for which I gave you bindings to use. I don't understand why you insist on doing things differently, but you can. Take a look at many other bindings how they achieve this - there are many, many examples. But do not invent third or fourth method... Best regards, Krzysztof
