This is okay, so there is no ABI break.

This is a bit odd... you have 7 devices which are simply compatible or
even the same. This should be instead one compatible.
I don't really get why do you want to deprecate "qcom,crypto-v5.1".
Commit msg only says "we decided" but I do not know who is "we" and "why
we decided like this". If you want to deprecate it, perfectly fine by
me, but please say in commit msg why you are doing it.
Best regards,
Krzysztof
