Subject: [PATCH net-next v2 0/3] 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.

Ivan Vecera (3):
  dpll: add phase-offset-avg-factor device attribute to netlink spec
  dpll: add phase_offset_avg_factor_get/set callback ops
  dpll: zl3073x: Allow to configure phase offset averaging factor
