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 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 the idle=nop patches I sent out earlier today, and is still unstable, even with those.
