This adds device trees for the following devices: - Macbook Air (M2, 2022) - Macbook Pro 13" (M2, 2022) - Mac mini (M2, 2023) This brings the hardware support of the machines to the same level as M1 and M1 Pro / Max / Ultra. Supported hardware include NVMe, PCIe, serial, pinctrl/gpio, I2C, iommu, watchdog, admac, nco, cpufreq, boot framebuffer for laptop panels and the interrupt controller. The ethernet LAN device on the M2 Mac mini is the only working PCIe device. The Wlan/BT devices are powered off and controlled by the not yet supported SMC. The ASMedia xHCI on the M2 Mac mini requires firmware to be loaded at startup. The main missing hardware support to make these devices useful are the integrated USB 2/3/4 controller, keyboard and trackpad on the laptops and SMC to power the PCIe Wlan/BT device on. The M2 Mac mini has currently no working display output. Due to changes in the display pipeline it is currently not possible to initialize the HDMI output in the bootloader.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
