The control of HMAX documented in the datasheet is consistent with being in terms of a scaled INCK, being always 72MHz or 74.25MHz. It is NOT link frequency dependent, but the minimum value for HMAX is dictated by the link frequency. If PIXEL_RATE is defined as being 12 times the 72 or 74.25MHz, and all values are scaled down again when writing HMAX, then the numbers all work out regardless of INCK or link frequency. Retain an hmax_min (set to the same value as the previous fixed hmax register value) to set as the default value to avoid changing the behaviour for existing users.

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.
