I ran rngtest and this is what I got:
This is meaningless except for sources that have not been whitened.

Your justification needs to be based on what the hardware does or
is documented to do.
Ok, so I guess that we’re never setting that value to anything since there’s
no public documentation about that ¯\_(ツ)_/¯.
@Florian, is there a way you might be able to get the official value?
I will be looking into the documentation this weekend and let you know
whether we can change the driver's quality accordingly.
Could you do that for iproc-rng200.c too?
