Hi Rahul,
Initially, I wanted to make a very generic driver and to add bit and
register (or its offset) attribute to the PHY node.
However, there was a very strong opposition from DT maintainers
to adding any bit related configuration to DT.
The current solution was designed to be a trade-off between
being generic and being accepted :).
