clk_bulk_get_optional() allows to get a group of clocks where one
or more is optional. For a not available clock, e.g. not specifed
in the clock consumer node in DT, its respective struct clk pointer
will be NULL. This allows for operating on a group of returned
clocks (struct clk_bulk_data array) with existing clk_bulk* APIs.

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.
