The current code only rely on the parent to change its rate in the case where CLK_SET_RATE_PARENT is set. However, some clock rates might be obtained only through a modification of the parent and the clock divider. Just rely on the round rate of the clocks to give us the best computation that might be achieved for a given rate. round_rate functions now need to honor CLK_SET_RATE_PARENT, but either the functions already do that if they modify the parent, or don't modify the praents at all.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
