Like A33 "sun4i-ss" has a difference, it give SHA1 digest
directly in BE. So add new compatible.

If it's compatible with the A33, why do we need to introduce a new compatible?

I guess the A33 compatible should be on that list as well?

This is the list of "need reset".
So we cannot use allwinner,sun8i-a33-crypto
Probably this explanation should be in the commit message.

But the A33 has a reset in the DTSI



Oh right so I need to send a fix for that and Martin Cerveny could simply use the "allwinner,sun8i-a33-crypto" (and so keep only patch #1(DTS))

Regards


What is "right" solution for DTSI ?
- compatible = "allwinner,sun8i-a33-crypto";
OR
- compatible = "allwinner,sun8i-v3s-crypto", "allwinner,sun8i-a33-crypto";
(but unimplemented "allwinner,sun8i-v3s-crypto")

Regards
