'reg' (and the unit-address) is an address in the sense that is how
you identify a device or sub-device. It doesn't matter what type of
'address' it is, DT practice is to sort node in unit-address numerical
order.
'module' is a h/w thing, right? A bank or instance within the device?
If not, using 'reg' here is not appropriate.
