On the RZ/T2H SoC, a specific sequence is required when releasing a module from the module stop state (i.e. when clearing the corresponding bit in the MSTPCRm register to '0'). After writing to the MSTPCRm register, a read-back of the same register must be performed, followed by at least seven dummy reads of any register within the IP block that is being released. To avoid mapping device registers for this purpose, a short delay is introduced after the read-back to ensure proper hardware stabilization before the module becomes accessible.

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.
