In fact, the en_mask is a combination of divider enable mask and pll enable bit(bit0). Before this patch, we enabled both divider mask and bit0 in prepare(), but only cleared the bit0 in unprepare(). In the future, we hope en_mask will only be used as divider enable mask. The enable register(CON0) will be set in 2 steps: first is divider mask, and then bit0 during prepare(), and vice versa. But considering backward compatibility, at this stage we allow en_mask to be a combination or a pure divider enable mask. And then we will make en_mask a pure divider enable mask in another following patch series.

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.
