Dual license please.
Sure, I will change it in v2.

Can one convert index to register/bit offset? If you can avoid made up
numbers and use something that corresponds to the h/w, that's preferred.
Unfortunately, only part of these clocks are related to registers or bits,
and the rest are not related to both, so we can't perform the kind of
conversion you mentioned.
Thanks and best regards!
