[PATCH net-next v2 0/2] dpll: Add support for phase adjustment granularity

[Ivan Vecera <ivecera@redhat.com>]

Phase-adjust values are currently limited only by a min-max range. Some
hardware requires, for certain pin types, that values be multiples of
a specific granularity, as in the zl3073x driver.

Patch 1: Adds 'phase-adjust-gran' pin attribute and an appropriate
         handling
Patch 2: Adds a support for this attribute into zl3073x driver

Changes:
v2:
* changed type for the attribute to u32 and added explicit cast to s32 during
  remainder computation (per Jiri's request) 

Ivan Vecera (2):
  dpll: add phase-adjust-gran pin attribute
  dpll: zl3073x: Specify phase adjustment granularity for pins
