====================
IXP46x PTP Timer clean-up and DT

ChangeLog v2->v3:

- Dropped the patch enabling compile tests: we are still dependent
  on some machine-specific headers. The plan is to get rid of this
  after device tree conversion. We include one of the compile testing
  fixes anyway, because it is nice to have fixed.

- Rebased on the latest net-next
