Fundamentally, device properties (in DT or ACPI) exist to describe the hardware in a generic and abstract fashion. It's a slippery slope from saying "you don't need this property because you know you whether you are on the *foo* architecture", to saying "you don't this property because you know whether you're on a Assabet or not." I think it's wrong to go down that path. -- dwmw2 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
