The previous algorithm hardcoded details about how the TCU clocks work. The new algorithm will use clk_round_rate to find the perfect clock rate for the PWM channel. This code relies on the fact that clk_round_rate() will always round down, which is not a valid assumption given by the clk API, but only happens to be true with the clk drivers used for Ingenic SoCs. Right now, there is no alternative as the clk API does not have a round-down function (and won't have one for a while), but if it ever comes to light, a round-down function should be used instead.

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.
