[PATCH 0/7] NVMe support for Apple M3, M3 Pro and M3 Max/Ultra devices

[Janne Grunau]

Hej,

this series adds NVMe support to all M3, M3 Pro and M3 Max/Ultra
devices. The hardware works the same way as T602x (M2 Pro/Max/Ultra). If
there were changes they don't affect the way the existing Linux drivers
use the hardware. So this series adds new per-SoC compatible strings to
the mailbox, SART (IOMMU) and ANS (NVMe host controller) bindings and
the device nodes.

Merge strategy:
The nvme tree has "dt-bindings: nvme: Add apple,t8132-nvme-ans2
compatible" [1] queued for apple,nvme-ans.yaml so "dt-bindings:
nvme: apple: Add Apple M3 compatibles" should go through the nvme tree
as well. The MAINTAINERS update can go with it.
The other dt-binding changes are trivial so there is a slight preference
to take them to the apple-soc tree with Acked-by: by their maintainers.
This keeps the number of `make dtbs_check` warnings in the apple-soc
tree low. Merging them through their maintainer's trees is not a
problem either.
The apple device tree changes are based on / depend on commit
eea4f3b5e9e1 ("Merge patch series "dt-check-style strict fixes for Apple
M3, M3 Pro/Max/Ultra"") apple-soc/dt-7.4.

I intentionally omitted the Fixes: in the MAINTAINERS update as I don't
see any value in adding this change to stable releases.
