The change

The internal keyboard and trackpad are HID devices behind the MTP's
DockChannel FIFO (ADT /arm-io/dockchannel-mtp/mtp-transport, with the
multi-touch, keyboard, stm, actuator and tp-accel children). Describe the
transport as t6050-j716s.dts does, with the J714s trackpad firmware name.
Its AFE reset is the ADT mtp function-afe-reset, SMC pcIO template
(0x10000, 0x11c0000), which is SMC GPIO gp1c, so the unused pcIO node
goes. The keyboard alias lets the loader fill the layout from the ADT's
keyboard node.

The keyboard backlight is the ADT pwm0/kbd-backlight at 25 kHz
(default-hz 25000), channel 0 of the fast PWM, as on J716s.

The M5 Pro's default SSD boot has run these nodes from its DT overlay
since 2026-11-09: Hyprland sees apple-mtp-keyboard and
apple-mtp-multi-touch.

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.
