The stm32_rng_read() function samples TRNG by 4 bytes until at least 5 bytes are free in the input buffer. The last four bytes are never read. For example, 60 bytes are returned in case the input buffer size is 64 bytes. Read until at least 4 bytes are free in the input buffer. Fill the buffer entirely in case the buffer size is divisible by 4.

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.
