[PATCH 0/9] 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.
Changes for the interrupt controller were sent separately in [1] and are
picked up and in linux-next. The device trees pass make dtbs_check with
the apple,aic2 dt-bindings change from that series.

[PATCH 8/9] 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 9/9] 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.
