The Crypto Engine is a hardware cryptographic offloader that supports
many algorithms.
It could be found on most Allwinner SoCs.

This patch enables the Crypto Engine on the Allwinner R40 SoC Device-tree.

The driver will probe if status is not declared, so if you want it
always enabled you should simply remove status
