Actually I'm not a big fan of the standard here in this regard.
"crypto@480a5000" doesn't mean anything and serves no purpose for
anyone. There are quite a few crypto modules and such a name doesn't
help and is confusing at best.

There's no property either in the device tree node itself to describe it
as des, except for the phandle label which is used only at dt
compile-time if I'm right. So makes sense to have the name be more specific.

This is how we have added dts nodes for other crypto modules in the past...

thanks,
