Recent Rockchip SoCs have a new hardware block called Native Interface Unit (NIU), which gates clocks to devices behind them. These clock gates will only have a running output clock when all of the following conditions are met: 1. the parent clock is enabled 2. the enable bit is set correctly 3. the linked clock is enabled To handle them this code registers them as a normal gate type clock, which takes care of condition 1 + 2. The linked clock is handled by using runtime PM clocks. Handling it via runtime PM requires setting up a struct device for each of these clocks with a driver attached to use the correct runtime PM operations. Thus the complete handling of these clocks has been moved into its own driver.

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 reStructuredText 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.
