[PATCH v2 0/9] Initial Apple Silicon M4 device trees and dt-bindings

[Yureka Lilian]

Hi,

This series adds initial device trees and dt-bindings for the Apple
Silicon devices using the M4 (t8132) SoC. For the most part it mirrors
Janne's M3 (t8122) bringup series as it was merged in the 7.2 cycle.

This series covers only a minimal amount of hardware, which is useful
as a basis for future developments. The hardware added here has remained
largely unchanged between the M3 and M4 generations.

Most of the changes for bringing these M4 devices into a bootable state
have been happening in the m1n1 bootloader, which, compared to the M3
generation, is no longer responsible for setting the configuration bits
(🐔-bits) of the CPU, since these are now set and locked by iBoot.  

Additionally, SMP boot depends on patches to avoid WFI and WFIT
instructions, such as the idle=nop patches I sent out just before v1.
Even with those, SMP boot remains unreliable.

Since there are no actual driver changes, we'd generally prefer to merge
the dt-bindings changes through the apple-soc tree once Acked by the
respective maintainers.
There are two notable exceptions in this patch series, due to some
commits having already been applied to the respective subsystems' trees:
- "dt-bindings: watchdog: apple,wdt: Add t8132 compatible"[1] has already
  been applied to the watchdog subsystem tree, and this patch series
  will pass check_dtbs when applied on top of linux-next, which includes
  that commit.
- "dt-bindings: pinctrl: apple,pinctrl: Add t8132 compatible" should be
  applied through the pinctrl tree, since it depends on
  "dt-bindings: pinctrl: apple,pinctrl: Add t6030 and t6031 compatibles"[2]
  which has been applied in the pinctrl tree.

Changes in v2:
- Rebased on top of the M3 Pro/Max patch series, which was applied to
  apple-soc earlier today.
- Fix several typos
- Explain merge strategy in cover letter
- Drop "dt-bindings: watchdog: apple,wdt: Add t8132 compatible", as it's
  been applied in linux-watchdog.
- Reword dt-bindings commit messages to not reference the driver
- Add apple,always-on to ps_ans node, since powering it off causes reboots
- Disable ps_disp*_cpu nodes, since even reading their state causes
  SErrors with recent firmware
- Fix inconsistency of name and reg of aic node
- Add M4 devices to the global description in Documentation/devicetree/bindings/arm/apple.yaml
- Link to v1: https://patch.msgid.link/20260705-apple-m4-initial-devicetrees-v1-0-e5655ee56523@cyberchaos.dev

[PATCH v2 1/9] dt-bindings: arm: cpus: Add Apple M4 CPU core compatibles

[Yureka Lilian]

The core types of the M4 SoC no longer carry individual codenames.
Apple's device trees re-use the 'everest' and 'sawtooth' codenames from
the M3 generation for all later cores.

Instead, we use a combination of the SoC's codename ('Donan') and the
type of core ('e' and 'p' for the efficiency and performance cores
respectively) as compatible for these cores.

[PATCH v2 9/9] arm64: dts: apple: Add minimal t8132 (M4) device trees

[Yureka Lilian]

Added device trees for the following devices:
- apple,j604 - MacBook Pro (14-inch, M4, 2024)
- apple,j623 - iMac (24-inch, 2x USB-C, M4, 2024)
- apple,j624 - iMac (24-inch, 4x USB-C, M4, 2024)
- apple,j713 - MacBook Air (13-inch, M4, 2025)
- apple,j715 - MacBook Air (15-inch, M4, 2025)
- apple,j773g - Mac mini (M4, 2024)

The device trees have a minimal set of devices limited to CPU cores,
interrupt controller, power states, watchdog, serial, pin controller,
i2c and framebuffer.
The device trees for the notebooks add a PWM controller for the keyboard
LED illumination.

Using the macOS 26.6 iBoot/firmware, the Mac mini reliably boots on a
single core using the stock kernel.
Booting with smp requires avoiding the wfi and wfit instructions
in the idle loop and `delay()` respectively, since those instructions
cause a loss of architectural state on the secondary cores, and even
then boot is unreliable.
