We seem to rely on the number of phandles specified in the 'required-opps' property to identify cases where a device is associated with multiple power domains and hence would have multiple virtual devices that have to be dealt with. In cases where we do have devices with multiple power domains but with only one of them being scalable, this logic seems to fail. Instead read the number of power domains from DT to identify such cases.

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.
