Sorry, I've realize that.
The fact is that: when put the include into the crypto at xxxx, it can't compile success(make c293pcie.dtb as example). Error will show as:

ERROR (duplicate_node_names): Duplicate node name /soc at fffe00000/crypto at 80000/jr at 1000

Since it will compile error in this way, so will not output .dtb file
