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` depends on the already applied and dropped apple,i2c\nand apple,pmgr dt-binding changes.\nThe watchdog load depends on stalled and forgotten addition of the\n\"apple,t8103-wdt\" compatible posted in [1]. I've replied to the thread\nto get the change merged.\n\nMerge strategy:\nApply whole series via apple-soc / arm-soc to keep `make dtbs_check`\nerrors minimal. Otherwise no dependencies between the patches.\nI might want to send another series which depends on this later in this\ncycle.\n\nLink: https://lore.kernel.org/linux-watchdog/20251231-watchdog-apple-t8103-base-compat-v1-1-1702a02e0c45@jannau.net/ [1]\nSigned-off-by: Janne Grunau <j@jannau.net>\n---\nChanges in v3:\n- adjust reg size of pmgr node to fit all its childrens' regs.
