If you claim this is a PCI device thus you do not need any resources, then the binding is not needed either. PCI devices are enumerable. And to prove it: look at your DTS. Do you see qcom,qcc2072-bt being used?

Drop the binding, you do not need it. Anyway the problem is that more comments were ignored. And why this is sent so many times? https://lore.kernel.org/all/[email protected]/ https://lore.kernel.org/all/[email protected]/ and now by you. How many times this will be sent in separate patchsets and asking for separate review ignoring previous review? Best regards, Krzysztof
