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.

zynqmp_get_divider2_val() calculates, divider value of type DIV2 clock, considering best possible combination of DIV1 and DIV2. To find best possible values of DIV1 and DIV2, DIV1's parent rate should be consider and not DIV2's parent rate since it would rate of div1 clock. Consider a below topology, out_clk->div2_clk->div1_clk->fixed_parent where out_clk = (fixed_parent/div1_clk) / div2_clk, so parent clock of div1_clk (i.e. out_clk) should be divided by div1_clk and div2_clk. Existing code divides parent rate of div2_clk's clock instead of div1_clk's parent rate, which is wrong. Fix the same by considering div1's parent clock rate.
