Initially, the helper dev_pm_opp_get_opp_table() was supposed to be used only for the OPP core's internal use (it tries to find an existing OPP table and if it doesn't find one, then it allocates the OPP table). Sometime back, the cpufreq-dt driver started using it to make sure all the relevant resources required by the OPP core are available earlier during initialization process to properly propagate -EPROBE_DEFER. It worked but it also abused the API to create an OPP table, which should be created with the help of other helpers provided by the OPP core. The OPP core will be updated in a later commit to limit the scope of dev_pm_opp_get_opp_table() to only finding an existing OPP table and not create one. This commit updates the cpufreq-dt driver before that happens. Now the cpufreq-dt driver creates the OPP and cpufreq tables for all the CPUs from driver's init callback itself.

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.
