[PATCH v2 0/5] Apple device tree sync from downstream kernel

[Janne Grunau]

This series pulls changes from the downstream device trees which are
supported in upstream kernel.
Most importantly it fixes the PCIe description for a specific iMac model
(iMac M1, 2 USB-C ports, 2021). This is worked around in the downstream
kernel by not disabling the port. In preparation for submitting M2
Pro/Max/Ultra devices trees I investigated the issue on the similarly
affected M2 Pro Mac mini and fixed it this way.
It completes the Wlan/BT device nodes for t600x based devices and adds
the missing 15-inch Macbook Air (M2, 2023).

Checkpatch emits following warnings:

WARNING: DT compatible string vendor "pci14e4" appears un-documented --
check ./Documentation/devicetree/bindings/vendor-prefixes.yaml

Which I chose to ignore. `vendor-prefixes.yaml` prefixes contains no
other mapping for PCI vendor code and the list of ignored prefixes
forbids extending it. Both options feel wrong though. "pci${vendor}" is
clearly a vendor prefix but duplicating the PCI vendor data base feels
wrong. `vendor-prefixes.yaml` currently does not contain and PCI vendor
aliases.

Changes in v2:
- fixed commit subject of PATCH 2/5
- correct Macbook Pro (15-inch, M2) to Macbook Air
- added Neal's and Sven's Rb: tags
- Link to v1: https://lore.kernel.org/r/20250813-apple-dt-sync-6-17-v1-0-209f15d10aa0@jannau.net

[PATCH v2 1/5] arm64: dts: apple: t8103-j457: Fix PCIe ethernet iommu-map

[Janne Grunau]

PCIe `port01` of t8103-j457 (iMac, M1, 2 USB-C ports, 2021) is unused
and disabled. Linux' PCI subsystem assigns the ethernet nic from
`port02` to bus 02. This results into assigning `pcie0_dart_1` from the
disabled port as iommu. The `pcie0_dart_1` instance is disabled and
probably fused off (it is on the M2 Pro Mac mini which has a disabled
PCIe port as well).
Without iommu the ethernet nic is not expected work.
Adjusts the "bus-range" and the PCIe devices "reg" property to PCI
subsystem's bus number.

Fixes: 7c77ab91b33d ("arm64: dts: apple: Add missing M1 (t8103) devices")

[PATCH v2 5/5] arm64: dts: apple: Add devicetreee for t8112-j415

[Janne Grunau]

The 15-inch M2 MacBook Air was released a year after the 13-inch one
thus missed in initial submission of devicetrees for M2 based devices.
It is currently a copy of t8112-j413 with edited identifiers but will
eventually differ in a meaningful way. It has for example a different
speaker configuration than the 13-inch model.
