The E825-C hardware has a slightly different register layout for register 19 of the Clock Generation Unit and TSPLL. The fbdiv_intgr value can be 10 bits wide. Additionally, most of the fields that were in register 24 are made available in register 23 instead. The programming logic already has a corrected definition for register 23, but it incorrectly still used the 8-bit definition of fbdiv_intgr. This results in truncating some of the values of fbdiv_intgr, including the value used for the 156.25MHz signal. The driver only used register 24 to obtain the enable status, which we should read from register 23. This results in an incorrect output for the log messages, but does not change any functionality besides disabled-by-default dynamic debug messages. Fix the register definitions, and adjust the code to properly reflect the enable/disable status in the log messages.

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.
