Drivers for CAAM(HW Cryptographic Accelerator) in iMX6S.

How we can access the hardware cryptographic accelerator i.e. CAAM in Freescale’s iMX6S processor for encryption i.e. AES-256 and hash message digest calculations i.e. SHA-256?
Do we have any drivers/libraries for the same?
Also any application to test the same.

Zaheer.
