  "message": "dpll: zl3073x: report FFO as DPLL vs input reference offset\n\nReplace the per-reference frequency offset measurement (which was\nredundant with measured-frequency) with a direct read of the DPLL\u0027s\ndelta frequency offset vs its tracked input reference.\n\nThe new implementation uses the dpll_df_offset_x register with\nref_ofst\u003d1 via the dpll_df_read_x semaphore mechanism. This\nprovides 2^-48 resolution (~3.5 fE) and reports the actual\nfrequency difference between the DPLL and its active input.\n\nSwitch supported_ffo from DPLL_FFO_PORT_RXTX_RATE to\nDPLL_FFO_PIN_DEVICE so FFO is reported only in the per-parent\ncontext for the active input pin.\n\nUse atomic64_t for freq_offset to prevent torn reads on 32-bit\narchitectures between the periodic worker and netlink callbacks.\n\nRewrite ffo_check to compare the cached df_offset converted to PPT\ninstead of using the old per-reference measurement. Remove the\nref_ffo_update periodic measurement and the ref ffo field since\nthey are no longer needed.\n\nChanges v3 -\u003e v4:\n- Switch to DPLL_FFO_PIN_DEVICE, remove dpll\u003dNULL guard\n- Use atomic64_t for freq_offset (torn read on 32-bit)\n\nReviewed-by: Petr Oros \u003cporos@redhat.com\u003e\nSigned-off-by: Ivan Vecera \u003civecera@redhat.com\u003e\nLink: https://patch.msgid.link/20260511155816.99936-3-ivecera@redhat.com\nSigned-off-by: Jakub Kicinski \u003ckuba@kernel.org\u003e\n",
