[PATCH iwl-net v7 0/3] ice: fix missing dpll notifications for SW pins

[Petr Oros <poros@redhat.com>]

The SMA/U.FL pin redesign never propagated dpll notifications to the
software-controlled pin wrappers.  This series fixes that in two steps
plus a prerequisite dpll core change.

Patch 1 exports __dpll_pin_change_ntf() so ice can send peer
notifications from callback context where dpll_lock is already held.

Patch 2 fixes HW-to-SW notification propagation: periodic work now
notifies SW wrappers when their backing CGU input changes, and
phase_offset reporting for SW pins reads the backing pin's value.

Patch 3 adds SW-to-SW peer notification: when SMA or U.FL pin state
changes via PCA9575 routing, the paired pin gets a dpll change event.

Ivan Vecera (1):
  dpll: export __dpll_pin_change_ntf() for use under dpll_lock

  ice: add dpll peer notification for paired SMA and U.FL pins

v7:
 - split ice patch into two: HW-to-SW notification propagation and
   SW-to-SW peer notification (requested by Jiri Pirko)
 - drop spurious blank line removal in ice_dpll_sma_direction_set()
