If st,rng-lock-conf is set, the RNG configuration in RNG_CR, RNG_HTCR
and RNG_NSCR will be locked. It is supported starting from the RNG
version present in the STM32MP13

How did you implement the comment? There is no changelog, so was it ignored?

Best regards,

I've sent V2 before Rob's review. I'll apply Rob's comment for V3.
