It only covers a minimal amount of hardware, but is nontheless useful for further development work. The hardware added here has remained largely unchanged from the earlier generation Apple Silicon Macs. Similar to the M4 devices, changes to the m1n1 bootloader are required to boot Linux on the MacBook Neo. Also, SMP boot depends on further patches to avoid WFI and WFIT instructions [1][2]. Merge strategy: Since there are no actual driver changes in this series, we'd prefer to merge the dt-bindings changes through the apple-soc tree once Acked by the respective maintainers.
