TRNG "sample size" (the total number of entropy samples that will be taken during entropy generation) default / POR value is very conservatively set to 2500. Let's set it to 512, the same as the caam driver in U-boot (drivers/crypto/fsl_caam.c) does. This solves the issue of RNG performance dropping after a suspend/resume cycle on parts where caam loses power, since the initial U-boot setttings are lost and kernel does not restore them when resuming. Note: when changing the sample size, the self-test parameters need to be updated accordingly.

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.
