Current implementation of the genpd support over TI SCI uses a single genpd across the whole SoC, and attaches multiple devices to this. This solution has its drawbacks, like it is currently impossible to attach more than one power domain to a device; the core genpd implementation requires one genpd per power-domain entry in DT for a single device. Also, some devices like USB apparently require their own genpd during probe time, the current shared approach in use does not work at all. Switch the implementation over to use a single genpd per power domain entry in DT. The domains are registered with the onecell approach, but we also add our own xlate service due to recent introduction of the extended flag for TI SCI PM domains; genpd core xlate service requires a single cell per powerdomain, but we are using two cells.

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.
