The OPP core currently requires the required opp tables to be available before the dependent OPP table is added, as it needs to create links from the dependent OPP table to the required ones. This may not be convenient for all the platforms though, as this requires strict ordering for probing the drivers. This patch allows lazy-linking of the required-opps. The OPP tables for which the required-opp-tables aren't available at the time of their initialization, are added to a special list of OPP tables: lazy_opp_tables. Later on, whenever a new OPP table is registered with the OPP core, we check if it is required by an OPP table in the pending list; if yes, then we complete the linking then and there. An OPP table is marked unusable until the time all its required-opp tables are available. And if lazy-linking fails for an OPP table, the OPP core disables all of its OPPs to make sure no one can use them.

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.
