changesetd5426f4c2e("media: staging: atomisp: use clock framework for camera clocks") removed a platform-specific code to set the clock rate, in favor of using the Kernel clock framework. However, instead of passing the frequency for clk_set_rate(), it is passing either 0 or 1. Looking at the original patchset, it seems that there are two possible configurations for the ISP: 0 - it will use a 25 MHz XTAL to provide the clock; 1 - it will use a PLL with is set to 19.2 MHz (only for the CHT version?) Eventually, different XTALs and/or PLL frequencies might be possible some day, so, re-implent the logic for it to be more generic.

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.
