[PATCH v2 0/6] Initial Apple silicon M3 device trees and dt-bindings

[Janne Grunau]

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.

[PATCH v2 5/6] dt-bindings: arm: apple: Add M3 based devices

[Janne Grunau]

The Apple devices with the t8122 SoC (M3) are very similar to their M1
and M2 predecessors.
Only the 13-inch Macbook Pro is replaced by a 14-inch version based on
the design of the 14-inch Macbook Pro with (M1/M2 Pro/Max). The Mac mini
was not offered with M3.

[PATCH v2 6/6] arm64: dts: apple: Initial t8122 (M3) device trees

[Janne Grunau]

Add minimal device trees for all t8122 based devices. The devices are
- iMac (24-inch, M3, 2023)
- MacBook Air (13-inch, M3, 2024)
- MacBook Air (15-inch, M3, 2024)
- MacBook Pro (14-inch, M3, 2023)

The device trees have a minimal set of devices limited to CPU cores,
interrupt controller, power states, watchdog, serial, pin controller,
i2c and the boot framebuffer.
The device trees for the notebooks add a PWM controller for the keyboard
LED illumination.
The iMacs and the 14-inch device trees add the i2c based Apple cd321x
USB Type-C port controller.
