Now that all the infrastructure is in place to support multiple required OPPs, lets switch over to using it. A new internal routine _set_required_opps() takes care of updating performance state for all the required OPPs. With this the performance state updates are supported even when the end device needs to configure regulators as well, that wasn't the case earlier. The pstates were earlier stored in the end device's OPP structures, that also changes now as those values are stored in the genpd's OPP structures. And so we switch over to using pm_genpd_opp_to_performance_state() instead of of_genpd_opp_to_performance_state() to get performance state for the genpd OPPs. The routine _generic_set_opp_domain() is not required anymore and is removed. On errors we don't try to recover by reverting to old settings as things are really complex now and the calls here should never really fail unless there is a bug. There is no point increasing the complexity, for code which will never be executed. Reviewed-by: Ulf Hansson <ulf.hansson@linaro.org> Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org>
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.
