I don't understand this part. Why do you include the name in the
gpios property, rather than just hardcoding the property strings
to "shutdown-gpios" and "reset-gpios"?
The description of hte "rfkill-name" property seems to suggest
that you can only have one logical RFKILL device per device node,
so he names would not be ambiguous.
