Cc'ing Stephen (as part of the device tree bindings maintainers > team) who was involved in that recent reset bindings discussion. I also thought about this, but the reset framework seems to be designed for "reset controller" IPs, i.e special IPs that are controlling reset signals. Looking at Documentation/devicetree/bindings/reset/reset.txt, I'm not sure to see how this would apply to GPIO-controlled reset signals.
