I think this is a good idea for kernel code, but not for bindings. We don't really want per register bindings. The problem with any generic/simple/basic binding is they always start that way. Then we add one property at a time not in any well planned way. I can easily come up with additions. For example, what about self-clearing reset bits. Or 2 bits per reset. Or multiple resets that have to be controlled together. 8 or 16-bit registers. IRQs and GPIOs could also be described in some cases with just groups of 32-bit registers for set,clear,status,mask,etc., but we don't do that in bindings for the same reasons. Rob
