According to Documentation/devicetree/bindings/arm/cpus.yaml, the "enable-method" property should be a property of the individual CPU nodes, and not of the parent "cpus" container node. However, on R-Car Gen2 and RZ/G1 SoCs, the property is tied to the "cpus" node instead. Secondary CPU bringup and CPU hot (un)plug work regardless, as arm_dt_init_cpu_maps() falls back to looking in the "cpus" node. The cpuidle code does not have such a fallback, so it does not detect the enable-method. Note that cpuidle does not support the "renesas,apmu" enable-method yet, so for now this does not make any difference.

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.
