The change

Audio is not brought up on J714s. ADT i2c1 holds the left sn012776
amplifiers (audio-speaker*) and i2c2 the cs42l84 codec
(audio-codec-output), so turn both buses off, as t6050-j716s.dts does.

The M5 Pro's default SSD boot has run with both off since 2026-11-09.

Testing (M5 Pro, J714s)

  • Already running: the M5 Pro's default SSD boot (kernel 7.3.0-m5-argb2) has run these exact nodes since 2026-11-09, from its kit and integration DT overlays.
  • In-tree check, run h1 (2026-11-10): that kernel, booted with a DTB built only from integration/aurora and this series, matches the overlay DT except for two properties:
    • apple,leakage-calibration-words, which are the unit's own fuse values;
    • a no-op t8112 cpufreq fallback compatible.
  • Same health checks as the overlay boot, all equal:
    • Hyprland on the panel at 3024x1964@120, Wi-Fi via NetworkManager, Bluetooth pairing;
    • camera 90/90 frames at 30 fps, keyboard and trackpad, both Type-C ports with two dwc3 controllers;
    • PMP running, CPU capacities 754/1024;
    • idle 6.20 W (overlay 6.22 W), one P thread at 4576 MHz (4590 MHz);
    • SEP read-only, no new dmesg warnings.
  • One difference, from the missing calibration words: gpubench copy bandwidth is 79 GB/s instead of 138, while light compute and render are unchanged. Without the words the driver doesn't apply J714's GPU controller defaults. Those words have to come from the loader, not a board DT.
  • Build: t6050-j714s.dtb builds with no dtc warnings. dtbs_check results follow in a comment.

The series edits t6050-j714s.dts at separate places, so its integration/aurora PRs merge in any order.
