When a clock is declared as both CGU_CLK_DIV and CGU_CLK_MUX, the CGU code expects the mux to be applied first, the divider second. On the JZ4760, and maybe on some other SoCs, some clocks also have a mux setting and a divider, but the divider is not applied to all parents selectable from the mux. This could be solved by creating two clocks, one with CGU_CLK_DIV and one with CGU_CLK_MUX, but that would increase the number of clocks. Instead, add a 8-bit mask to CGU_CLK_DIV clocks. If the bit corresponding to the parent clock's index is set, the divider is bypassed.

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.
