I've been working on a patch to support both *-gpios and *-gpio variants with the GPIO descriptor framework. *-gpios makes sense if there can indeed be several, but for something like hotplug detection I don't think there's a reason to require the plural. Furthermore some bindings already use the singular *-gpio anyway, so if we ever want to convert drivers using those bindings to the GPIO descriptor API we have to support that form too. Thierry
