Subject: [PATCH v6 0/9] crypto: caam - backlogging support
Date:   Wed, 12 Feb 2020 19:55:15 +0200
Message-Id: <1581530124-9135-1-git-send-email-iuliana.prodan@nxp.com>

Integrate crypto_engine framework into CAAM, to make use of
the engine queue.
Added support for SKCIPHER, HASH, RSA and AEAD algorithms.
This is intended to be used for CAAM backlogging support.
The requests, with backlog flag (e.g. from dm-crypt) will be
listed into crypto-engine queue and processed by CAAM when free.

While here, I've also made some refactorization.
Patches #1 - #4 include some refactorizations on caamalg, caamhash
and caampkc.
Patch #5 changes the return code of caam_jr_enqueue function
to -EINPROGRESS, in case of success, -ENOSPC in case the CAAM is
busy, -EIO if it cannot map the caller's descriptor.
Patches #6 - #9 integrate crypto_engine into CAAM, for
SKCIPHER/AEAD/RSA/HASH algorithms.

---
Changes since V5:
	- remove unnecessary initializations;
	- add local variable for share descriptor offset for skcipher and hash;
	- handle error case for ahash_update_first and ahash_update_no_ctx.

Changes since V4:
	- reorganize {skcipher,aead,rsa}_edesc struct for a proper
	  cacheline sharing.

Changes since V3:
	- update return on ahash_enqueue_req function from patch #9.

Changes since V2:
	- remove patch ("crypto: caam - refactor caam_jr_enqueue"),
	  that added some structures not needed anymore;
	- use _done_ callback function directly for skcipher and aead;
	- handle resource leak in case of transfer request to crypto-engine;
	- update commit messages.

Changes since V1:
	- remove helper function - akcipher_request_cast;
	- remove any references to crypto_async_request,
	  use specific request type;
	- remove bypass crypto-engine queue, in case is empty;
	- update some commit messages;
	- remove unrelated changes, like whitespaces;
	- squash some changes from patch #9 to patch #6;
	- added Reviewed-by.
