  "message": "ice: fix SMA and U.FL pin state changes affecting paired pin\n\nSMA and U.FL pins share physical signal paths in pairs (SMA1/U.FL1 and\nSMA2/U.FL2) controlled by the PCA9575 GPIO expander.  Each pair can\nonly have one active pin at a time: SMA1 output and U.FL1 output share\nthe same CGU output, SMA2 input and U.FL2 input share the same CGU\ninput.  The PCA9575 register bits determine which connector in each\npair owns the signal path.\n\nThe driver does not account for this pairing in two places:\n\nice_dpll_ufl_pin_state_set() modifies PCA9575 bits and disables the\nbacking CGU pin without checking whether the U.FL pin is currently\nactive.  Disconnecting an already inactive U.FL pin flips bits that\nthe paired SMA pin relies on, breaking its connection.\n\nice_dpll_sma_direction_set() does not propagate direction changes to\nthe paired U.FL pin.  For SMA2/U.FL2 the ICE_SMA2_UFL2_RX_DIS bit is\nnever managed, so U.FL2 stays disconnected after SMA2 switches to\noutput.  For both pairs the backing CGU pin of the U.FL side is never\nenabled when a direction change activates it, so userspace sees the\npin as disconnected even though the routing is correct.\n\nFix by guarding the U.FL disconnect path against inactive pins and by\nupdating the paired U.FL pin fully on SMA direction changes: manage\nICE_SMA2_UFL2_RX_DIS for the SMA2/U.FL2 pair and enable the backing\nCGU pin whenever the peer becomes active.\n\nFixes: 2dd5d03c77e2 (\"ice: redesign dpll sma/u.fl pins control\")\nSigned-off-by: Petr Oros \u003cporos@redhat.com\u003e\nTested-by: Alexander Nowlin \u003calexander.nowlin@intel.com\u003e\nReviewed-by: Arkadiusz Kubalewski \u003carkadiusz.kubalewski@intel.com\u003e\nSigned-off-by: Jacob Keller \u003cjacob.e.keller@intel.com\u003e\nLink: https://patch.msgid.link/20260427-jk-iwl-net-petr-oros-fixes-v1-8-cdcb48303fd8@intel.com\nSigned-off-by: Paolo Abeni \u003cpabeni@redhat.com\u003e\n",
