Currently the optional property opp-shared is used within an opp table to tell that a set of devices share their clock/voltage lines (and the OPP points). It is therefore possible to use an empty OPP table to convey only that information, useful in situations where the opp points are provided via other means (hardware. firmware, etc). Update the documentation to remark this additional case and provide an example. Signed-off-by: Nicola Mazzucato <nicola.mazzucato@arm.com> 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.
