Yeah this new lookup scheme probably does no harm, but I think it should be a little bit more motivated as it is, after all, introducing more potential confusion for DT users.
It does not look like this new lookup scheme is necessary to Chen-Yu's patchset and that he could as well have used the current one. Right now there is only one way to define GPIOs - if we introduce a second one, then which one should new DT users choose? Which one looks better? I can already endless fights taking place over this.
Does this new lookup help with some of the existing problems we have like ACPI/DT lookup compatibility?
I just need to be given one practical reason to give my ack.
Alex.
