FSL uses the internal reflck to implement the open_device() functionality, conversion to the core code is straightforward. The decision on which set to be part of is trivially based on the is_fsl_mc_bus_dprc() and we use a 'struct device *' pointer as the set_id. The dev_set lock is protecting the interrupts setup. The FSL MC devices are using MSIs and only the DPRC device is allocating the MSIs from the MSI domain. The other devices just take interrupts from a pool. The lock is protecting the access to this pool.

README
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.
