The\ndevice trees contain only a minimal set of hardware not going much\nbeyond the minimum required for booting kernel and initramfs and\nverify via serial console that the hardware and drivers work.\nThe hardware with the exception of the interrupt controller is\ncompatible with the M1 and M2 SoCs and the existing drivers.\n`make dtbs_check` fails due to already applied and dropped apple,i2c\ndt-bindings change (commit c5f25f5800f5 (\"dt-bindings: i2c: apple,i2c:\nAdd t8122 compatible\") in\nhttps://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git\ni2c/for-next).\n\nMerge strategy:\nApply whole series ivia apple-soc / arm-soc to keep `make dtbs_check`\nerrors minimal.
