[PATCH 0/3] Introduce the cypto engine framework

From: Baolin Wang
Date: Tue Jan 26 2016 - 07:26:38 EST

Now block cipher engines need to implement and maintain their own queue/thread
for processing requests, moreover currently helpers provided for only the queue
itself (in crypto_enqueue_request() and crypto_dequeue_request()) but they
don't help with the mechanics of driving the hardware (things like running the
request immediately, DMA map it or providing a thread to process the queue in)
even though a lot of that code really shouldn't vary that much from device to

This patch introduces the crypto engine framework to help the crypto hardware
drivers to queue requests.

Baolin Wang (3):
crypto: Introduce crypto_queue_len() helper function
crypto: Introduce the block request crypto engine framework
crypto: omap-aes: Support crypto engine framework
