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 Petr Oros (2): ice: fix missing dpll notifications for SW pins ice: add dpll peer notification for paired SMA and U.FL pins drivers/dpll/dpll_netlink.c | 10 +++ drivers/dpll/dpll_netlink.h | 2 - drivers/net/ethernet/intel/ice/ice_dpll.c | 79 +++++++++++++++++++---- include/linux/dpll.h | 1 + 4 files changed, 79 insertions(+), 13 deletions(-) --- 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() v6: https://lore.kernel.org/all/20260416113952.389405-1-poros@redhat.com/ v5: https://lore.kernel.org/all/20260409102501.1447628-1-poros@redhat.com/ v4: https://lore.kernel.org/all/20260319205256.998876-1-poros@redhat.com/ v3: https://lore.kernel.org/all/20260220140700.2910174-1-poros@redhat.com/ v2: https://lore.kernel.org/all/20260219131500.2271897-1-poros@redhat.com/ v1: https://lore.kernel.org/all/20260218211414.1411163-1-poros@redhat.com/
