Yep those quirks is what we have done to handle legacy cases, mostly from old devicetrees using bindings where proper polarity wasn't enforced or properly used because the drivers would override it anyway. Ideally the bindings schema should enforce consumers to use GPIO_ACTIVE_LOW but I don't know if that is possible, but maybe Krzysztof has ideas! Yours, Linus Walleij
