Async Kernel crypto API support for RSA ?

Hi Friends,

Does linux kernel's async crypto API support RSA operations(Asymmetric
ciphers)? I mean can my driver utilize my RSA crypto hardware
(assuming I have driver for the RSA hardware) using linux's async
kernel crypto API?
I see async interface is present in kernel only for symmetric cipher
(ablkcipher) and hash operations (ahash) and not able to locate the
same support for RSA?
