Merge branch '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue
Tony Nguyen says: ==================== Intel Wired LAN Driver Updates 2024-10-01 (ice) This series contains updates to ice driver only. Karol cleans up current PTP GPIO pin handling, fixes minor bugs, refactors implementation for all products, introduces SDP (Software Definable Pins) for E825C and implements reading SDP section from NVM for E810 products. Sergey replaces multiple aux buses and devices used in the PTP support code with struct ice_adapter holding the necessary shared data. * '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue: ice: Drop auxbus use for PTP to finalize ice_adapter move ice: Use ice_adapter for PTP shared data instead of auxdev ice: Initial support for E825C hardware in ice_adapter ice: Add ice_get_ctrl_ptp() wrapper to simplify the code ice: Introduce ice_get_phy_model() wrapper ice: Enable 1PPS out from CGU for E825C products ice: Read SDP section from NVM for pin definitions ice: Disable shared pin on E810 on setfunc ice: Cache perout/extts requests and check flags ice: Align E810T GPIO to other products ice: Add SDPs support for E825C ice: Implement ice_ptp_pin_desc ==================== Link: https://patch.msgid.link/20241001201702.3252954-1-anthony.l.nguyen@intel.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
