Subject: [PATCH 00/17] 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 ont the dart-t8110 bindings queued in
the iommu tree for 6.3 [1] and support for "local-mac-address" for
brcm,bcm4329-fmac based devices [2]. 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 PMU (performance monitor) driver needs a small update which I'll
send out separately. All other driver changes are already queued. The
dt-bindings changes should be merged through asahi-soc to ensure
devicetree validation.
