Marketing/acquistion renames was just an example and common reason. That doesn't make other reasons okay. I don't see any reason given here. If you want to break the ABI (do you??, because the commit message still doesn't say), then you don't need "ralink,mt7620-pinctrl". Rob

Otherwise you have now two valid compatibles which contradicts previous Rob's comments. > The driver still has it though, so old DTs will keep > working. That keeps the ABI intact regardless of deprecating strings on > the dt-binding schema, right? Yes, but deprecation is missing. Best regards, Krzysztof
