I didn't realize that was also required -- the make checks should have picked this up too? I might be invoking the tests incorrectly. I should add the ipq9574 in the same list as ipq8074-gen3 and ipq6018, correct? Alex

If you add new variant, look at existing compatibles where they appear. If there is a if: constraining compatibles, then it's a hint you should do the same for your device. So yes, you must constrain all properties which are made flexible in top-level properties. Best regards, Krzysztof

IPQ9574 has PCIe controllers which are almost identical to IPQ6018. The only difference is that the "iface" clock is not required. Document this difference along with the compatible string.
