+ *
+ * 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 reset registers returns zero
+ * (used for detection), writing any value causes the associated history to be
+ * reset.
+ * Virtual registers have to be handled in device specific driver code. Chip
+ * driver code returns non-negative register values if a virtual register is
+ * supported, or a negative error code if not. The chip driver may return
+ * -ENODATA or any other error code in this case, though an error code other
+ * than -ENODATA is handled more efficiently and thus preferred. Either case,
+ * the calling PMBus core code will abort if the chip driver returns an error
+ * code when reading or writing virtual registers.
