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.

3: https://lore.kernel.org/linux-devicetree/[email protected]/
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.

Changes in v2:
- collect acked/reviewed-by: tags
- disable unused PCIe ports instead of deleting them
- fixes based on review feedback for "apple,aic2" and "apple,sart"
- dropped "arm-pmu: Add PMU compatible strings for Apple M2 cores"
(submitted separately)
- Link to v1: https://lore.kernel.org/r/[email protected]

From: Hector Martin <[email protected]>
Add the apple,t8112-pmgr-pwrstate compatible for the Apple M2 SoC.
This goes after t8103. The sort order logic here is having SoC numeric
code families in release order, and SoCs within each family in release
order:
- t8xxx (Apple HxxP/G series, "phone"/"tablet" chips)
- t8103 (Apple H13G/M1)
- t8112 (Apple H14G/M2)
- t6xxx (Apple HxxJ series, "desktop" chips)
- t6000 (Apple H13J(S)/M1 Pro)
- t6001 (Apple H13J(C)/M1 Max)
- t6002 (Apple H13J(D)/M1 Ultra)
Note that t600[0-2] share the t6000 compatible where the hardware is
100% compatible, which is usually the case in this highly related set
of SoCs.

I'm not sure how these pci compatibles are usually handled. Do they have to
be added to the dt-bindings Documentation as well or is it fine to just have them
here since they're not really used to match anything?
Otherwise this looks good to me,

I suppose they have to be added (at least for dtb validation) but
"pci14e4,4433" is already in net/wireless/brcm,bcm4329-fmac.yaml. Added
via e2e37224e8b3 ("dt-bindings: net: bcm4329-fmac: Add Apple properties
& chips").
