Hej,
This series adds initial device trees for M3 Apple silicon devices. The
device trees contain only a minimal set of hardware not going much
beyond the minimum required for booting kernel and initramfs and
verify via serial console that the hardware and drivers work.
The hardware with the exception of the interrupt controller is
compatible with the M1 and M2 SoCs and the existing drivers.
`make dtbs_check` fails due to already applied and dropped apple,i2c
dt-bindings change (commit c5f25f5800f5 ("dt-bindings: i2c: apple,i2c:
Add t8122 compatible") in
https://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git
i2c/for-next).
Merge strategy:
Apply whole series ivia apple-soc / arm-soc to keep `make dtbs_check`
errors minimal. Otherwise no dependencies between the patches.
I might want to send another series which depends on this later in this
cycle.
