In the case of dp_en and pin_pol, the register is already used for different offsets, so presumably you're writing into don't care offsets? In the other cases, it just looks like a few new registers added for 3368 and 3399. In this scenario, I don't think it's that bad to just have separate structs for each version that has distinct features. There's going to be more duplication, but then it's super easy to understand which platform has which registers. The whole versioning system is a little strange. For example, is each version guaranteed to have the registered defined for the previous version (ie: 3.6 contains all registers defined for 3.5)?
