Enumerate all available DPLL channels and registers a DPLL device for each of them. Check all input references and outputs and register DPLL pins for them. Number of registered DPLL pins depends on configuration of references and outputs. If the reference or output is configured as differential one then only one DPLL pin is registered. Both references and outputs can be also disabled from firmware configuration and in this case no DPLL pins are registered. All registrable references are registered to all available DPLL devices with exception of DPLLs that are configured in NCO (numerically controlled oscillator) mode. In this mode DPLL channel acts as PHC and cannot be locked to any reference. Device outputs are connected to one of synthesizers and each synthesizer is driven by some DPLL channel. So output pins belonging to given output are registered to DPLL device that drives associated synthesizer. Finally add kworker task to monitor async changes on all DPLL channels and input pins and to notify about them DPLL core. Output pins are not monitored as their parameters are not changed asynchronously by the device.

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 reStructuredText 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.
