What is the point of having very generic final compatible in the binding which does not relate to actual hardware? Let's say next SoC will be apple,x-abcd-foo-2323-whatever-nothing-in-common and you still have to use generic "apple,pinctrl" even though HW is not at all compatible? This looks like wildcard, not HW description. Best regards, Krzysztof
