Merge branch 'dpll-add-phase-offset-averaging-factor'
Ivan Vecera says:
====================
dpll: add phase offset averaging factor
For some hardware, the phase shift may result from averaging previous values
and the newly measured value. In this case, the averaging is controlled by
a configurable averaging factor.
Add new device level attribute phase-offset-avg-factor, appropriate
callbacks and implement them in zl3073x driver.
