I meant a scenario where we need to support SE1 instance as well. There is one more SE instance in Tegra, which is very similar to SE2 AES Engine. But right now, it does not have a good use case in Linux. Now if we add nvidia,tegra234-se-aes and nvidia,tegra234-se-hash, when SE1 needs to be supported, I guess it would be confusing to find the right compatible for it. Regards, Akhil
