Until now all Raspberry Pi boards used the power off function of the SoC. But the Raspberry Pi 400 uses gpio-poweroff for the whole board which possibly cannot register the poweroff handler because the it's already registered by this watchdog driver. So consider the system-power-controller property for registering, which is already defined in soc/bcm/brcm,bcm2835-pm.txt .

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.
