As this patch is quite big and tend to accumulate quite a few comments
- both hard to track and to address - I'm wondering if splitting it in
a few separated patches would could help?

e.g. 

- 1 patch for dpll device struct && APIs definition
- 1 patch for pin related APIs
- 1 patch for netlink notification.

(to be considered only if the effort for the above split is not
overwhelming)

Possibly the same could apply to patch 5/8.

Cheers,

Paolo
