Yes for the APIs used in cryptd, but usually hardware driver does not
need to have any threads attached, since completion of the event is
handled in the interrupt handler.

No, there is no documentation except source code.
In some files you can even find this comments:
* HEAVY TODO: needs to kick Herbert XU to write documentation.
Herbert is a crypto maintainer who created async crypto interfaces you
found in cryptd. You can also check hardware crypto drivers in
drivers/crypto/ directory.
