Two different forms for the same property name is not great. Just make a new property if you need something different. Rob

Just make a > new property if you need something different. Thank you for reviewing the patch. Based on the discussion for the previous series at [1], I had planned to reuse the same property "ti,qsgmii-main-ports" for TI's J721e device too. The reason for this is that the property represents the same feature on both devices which is that of the QSGMII main port. The only difference between the two of them is that J7200's CPSW5G has 4 external ports while J721e's CPSW9G has 8 external ports. Thus, J7200 can have at most one QSGMII main port while J721e can have up to two. Adding a new property which describes the same feature appears to be redundant to me. Please let me know.

Did you test the bindings with your DTS? Yes, I tried it out with different compatibles in the DTS file for the node, making sure that the property "ti,qsgmii-main-ports" is allowed only for the "ti,j7200-cpsw5g-phy-gmii-sel" and the "ti,j721e-cpsw9g-phy-gmii-sel" compatibles. Additionally, I also tested that the "minItems", "maxItems", "minimum" and "maximum" checks apply. All of the rules within the "allOf", are enforced one after the other in sequence, based on my testing. Please let me know in case of any suggestions to implement it in a better way. Regards, Siddharth.

Thank you for reviewing the patch. I plan to update the description to the following: "Required only for QSGMII mode. Array to select the port/s for QSGMII main mode. The size of the array corresponds to the number of QSGMII interfaces and thus, the number of distinct QSGMII main ports, supported by the device. If the device supports two QSGMII interfaces but only one QSGMII interface is desired, repeat the QSGMII main port value corresponding to the QSGMII interface in the array." I intend to describe the property in detail to help users understand the property and its usage better. In the process, I might have unintentionally made it appear as two different properties in the previous description. I hope the new description shows that the property describes the same feature across devices while making its usage clear to the users at the same time. Please let me know if this is fine. Regards, Siddharth.

The last hunk with > "ti,qsgmii-main-ports: false" is in a if: with negation ("not:")? Yes, the newly added compatible "ti,j721e-cpsw9g-phy-gmii-sel" is placed within an "if:" followed by a "not:", along with the already existing "ti,j7200-cpsw5g-phy-gmii-sel" compatible. With this, "ti,qsgmii-main-ports" is allowed only for the aforementioned compatibles and disallowed for the rest. Regards, Siddharth.

TI's J721e SoC supports additional PHY modes like QSGMII and SGMII that are not supported on earlier SoCs. Add a compatible for it. Extend ti,qsgmii-main-ports property to support selection of upto two main ports at once across the two QSGMII interfaces.
