PLLs are the source clocks for the DDIs so in order to determine the ddi clock we need to check the PLL configuration. This gets a little tricky for ICL since there is no register bit that maps directly to the link clock. So this patch creates a separate function in intel_dpll_mgr.c to obtain the write array PLL Params and compares the set pll_params with the table to get the corresponding link clock. v2: - Fix the encoder type check (DK). - Improve our error checking, return a sane value (Mika, Paulo). - Fix table entries (Paulo).

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.
