/*
* Virtual registers.
* Useful to support attributes which are not supported by standard PMBus
* registers but exist as manufacturer specific registers on individual chips.
* Must be mapped to real registers in device specific code.
*
* Semantics:
* Virtual registers are all word size.
* READ registers are read-only; writes are either ignored or return an error.
* RESET registers are read/write. Reading returns zero (used for detection),
* writing any value causes the associated history to be reset.
