Subject: [PATCH v3 00/15] Device trees for Apple M2 (t8112) based devices
This series contains dt-bindings updates and device trees for Apple
silicon devices based on the M2 SoC (t8112).
Device tree validation depends on the dart-t8110 bindings queued in
the iommu tree for 6.3 [1], PMU updates [2] and support for
"local-mac-address" for brcm,bcm4329-fmac based devices [3]. The latter
fixes validation errors for the existing M1 and M1 Pro/Max/Ultra device
trees.
The device trees are tested with the downstream Asahi Linux kernel and
on top of v6.2-rc5. The hardware is of limited use with the upstream
kernel. The notebooks miss keyboard/trackpad drivers and usb support.
The Mac mini does not yet have a boot framebuffer and lacks usb support
as well.

The dt-binding changes in this series are documentation only. All
drivers are compatible with the HW on the M2 SoC and are probed based
on generic compatibles. The t8112 specific compatibles are added to
address t8112 specific quirks in the case they become required.
