Hello,

I would like to know if anyone has a tutorial/document link in writing a
CRYPTO_ALG_TYPE_ABLKCIPHER crypto device driver?  I am looking at
drivers/cipher/mv_cesa.c but there are lots of things going on which are
hardware context related.  I would like to know what the minimum
requirements for an asynchronous block cipher drivers are before I hand
over (DMA) the collected data to my encryption hardware.

Thanks in advance for your help!

Kind Regards,
Rodel
