The saved J316s (T6000) and J413 (T8112) hardware trees describe motion services, SPI4 and SPMI/PMIC endpoints that integration omits. Describe those endpoints using the existing motion, SPI, polled SPMI and NVMEM drivers, and document the additional compatibles. Also describe the existing T8112 DP-audio interface and remove its unused reset-domains properties. The per-board audit evidence is maintained outside the kernel tree. The PR diff contains DTS and existing bindings only.

Every new node is explicitly disabled; this is describe-only. The auxiliary PMIC NVMEM providers are read-only and sit below disabled buses. Motion children remain disabled pending loader calibration handoff and sample qualification. No calibration, firmware, tuning payload or per-unit identity is included.

Addresses are translated through each capture's arm-io/ranges. Only the polled SPMI register interface is modeled; no interrupt-controller mode, regulator map or bus-ownership transfer is enabled. Shared SoC includes propagate disabled controller descriptions to sibling boards; auxiliary PMIC and motion children stay in the captured board files. J316c is T6001 M1 Max, and has no own capture in this audit; it is not claimed qualified.

Validation is pending in a controller buildbox slot using DT2's unchanged apple-dt-check.sh <merge-base> <head> <workdir>: every Apple DTB at base/head, zero new warnings, and each of the five touched existing bindings checked. Additional W=1 comparisons cover all ten affected boards. Source is pinned to 165f4bd7ffcfd6d3f84dccb32d9c12f6d4111d28, merge base 1eac5facc8fdd19fa41eed674ab59d445c1d3d0e (includes the requested 6c7029b integration updates). Controller request h-50322 uses the unmodified script from the actual integration merge base and records its checksum, base, topic and synthetic merge IDs. This PR remains draft pending the results and hardware qualification.

The AOP core registers service devices itself without an explicit child-availability check. Thus child status = "disabled" is not claimed as a proven runtime gate; the motion driver's missing-calibration refusal independently leaves the sensors off. Availability handling must be qualified before loader handoff. No reference-Mac hardware or boot chain is changed by this work.

The topic is directly rebased onto integration (including #1112, #1029 and #1030), with two source-only commits and no other task branch merge. The check is performed on a merge into canonical integration, with conflict status recorded.

Both reference Macs now have the integration DTB delivery path; these changes can be carried by a DTB-set refresh. DT2 will hardware-test on M2 after source/CI completion; M1 Pro is offline until an operator power-cycle. No hardware test is claimed. The gap reports are kept outside this PR and distinguish unsupported firmware/driver functions from DT descriptions. Existing JPEG, WLAN wake, PMP, AVD PIODMA and T600x DP-audio work is tracked without duplication. The integrated Stockholm model profile still needs older-follower identity and IRQ-mapping qualification before these boards can use its compatible.

Debug-port, processor-trace, sac-manager and nco-service endpoints are waived under DT2 Addendum 3. No such nodes or bindings are added. The readiness marker remains withheld pending the actual merge/CI result.

Current verification status: merge-as-integration check h-50322 is approved but queued; no compile/schema pass or readiness handoff is claimed. The rebased topic contains two source-only commits, with all 20 new nodes explicitly disabled and no kernel audit documents or new binding files.
