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.

Best regards,
