Hello Greg & Sasha, I would like to ask you for your opinion about
backporting DTS patches to stable kernel which allows usage of hwrng on
Marvell Armada 3700 devices.
Driver is already part of 5.4 kernel, just DTS bindings are not there.
I do not know if such backport is suitable for stable kernels. In file
https://www.kernel.org/doc/html/latest/process/stable-kernel-rules.html
is written that "New device IDs and quirks are also accepted" where
"device id" could mean also small DTS change...
What do you think? Question is about these 3 small commits:

We could, that's how I've been parsing that rule.

If it was actually tested on 5.4, I could queue it up for the next
release cycle.

Hello Sasha! Now I tested these patches on top of stable 5.4 and hwrng
is working fine.
