Device-tree parsing happens twice, once while deciding idle state to be used for hotplug and once during cpuidle init. Hence, parsing the device tree and caching it will reduce code duplication. Parsing code has been moved to pnv_parse_cpuidle_dt() from pnv_probe_idle_states(). In addition to the properties in the device tree the number of available states is also required.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
