Antoine Tenart 082ec2d484 crypto: inside-secure - add support for HMAC updates
This patch adds support for HMAC updates in the Inside Secure SafeXcel
crypto engine driver. Updates were supported for hash algorithms, but
were never enabled for HMAC ones. This fixes boot time test issues.

Antoine Tenart 57660b11d5 crypto: inside-secure - implement IV retrieval
This patch adds support for retrieving intermediate IV from the crypto
engine when using the CBC block mode with AES and (3)DES. The retrieved
IV is copied to the request IV buffer, as requested by the kernel crypto
API.

This fix boot tests added by
commit 8efd972ef9 ("crypto: testmgr - support checking skcipher output IV").

Ofer Heifetz 9744fec95f crypto: inside-secure - remove request list to improve performance
This patch main goal is to improve driver performance by moving the
crypto request from a list to a RDR ring shadow.

This is possible since there is one producer and one consume for this
RDR request shadow and one ring descriptor is left unused.
Doing this change eliminates the use of spinlock when accessing the
descriptor ring and the need to dynamicaly allocate memory per crypto
request.

The crypto request is placed in the first RDR shadow descriptor only
if there are enough descriptors, when the result handler is invoked,
it fetches the first result descriptor from RDR shadow.

The ORO bridge (connected to the EIP197 write channel) does not
generate back pressure towards the EIP197 when its internal FIFO is

Antoine Tenart 7d8f52a30d crypto: inside-secure - use precise compatibles
At first we used two compatibles in the SafeXcel driver, named after the
engine revision: eip97 and eip197. However this family of engines has
more precise versions and in fact we're supporting the eip97ies and
eip197b. More versions will be supported in the future, such as the
eip197d, and we'll need to differentiate them.

This patch fixes the compatibles used in the driver, to now use precise
ones. The two historical compatibles are kept for backward
compatibility.

Antoine Tenart f7268c538b crypto: inside-secure - keep the requests push/pop synced
This patch updates the Inside Secure SafeXcel driver to avoid being
out-of-sync between the number of requests sent and the one being
completed.

The number of requests acknowledged by the driver can be different than
the threshold that was configured if new requests were being pushed to
the h/w in the meantime. The driver wasn't taking those into account,
and the number of remaining requests to handled (to reconfigure the
interrupt threshold) could be out-of sync.

This patch fixes it by not taking in account the number of requests
left, but by taking in account the total number of requests being sent
to the hardware, so that new requests are being taken into account.

Antoine Ténart 871df319bd crypto: inside-secure - EIP97 support
The Inside Secure SafeXcel driver was firstly designed to support the
EIP197 cryptographic engine which is an evolution (with much more
feature, better performances) of the EIP97 cryptographic engine. This
patch convert the Inside Secure SafeXcel driver to support both engines
(EIP97 + EIP197).

The main differences are the register offsets and the context
invalidation process which is EIP197 specific. This patch adds an
indirection on the register offsets and adds checks not to send any
invalidation request when driving the EIP97. A new compatible is added
as well to bind the driver from device trees.

Antoine Ténart dc7e28a328 crypto: inside-secure - dequeue all requests at once
This patch updates the dequeueing logic to dequeue all requests at once.
Since we can have many requests in the queue, the interrupt coalescing
is kept so that the ring interrupt fires every EIP197_MAX_BATCH_SZ at
most.

To allow dequeueing all requests at once while still using reasonable
settings for the interrupt coalescing, the result handling function was
updated to setup the threshold interrupt when needed (i.e. when more
requests than EIP197_MAX_BATCH_SZ are in the queue). When using this
capability the ring is marked as busy so that the dequeue function
enqueue new requests without setting the threshold interrupt.

Antoine Ténart 86671abbbb crypto: inside-secure - use one queue per hw ring
Update the inside-secure safexcel driver from using one global queue to
one queue per hw ring. This ease the request management and keep the hw
in sync with what's done in sw.

Igal Liberman ee1fd870ee crypto: inside-secure - optimize DSE bufferability control
Configure the data write bufferability to always buffer packets in the
DSE. This change slightly improves performance.

Igal Liberman c87925bfd2 crypto: inside-secure - enable single WR in DSE configuration
When enable_single_wr is not enabled, the DSE will only write those
parts of a result descriptor that need updating, which means a final
result descriptor will be written in 2 or 3 smaller transfers.
When enable_single_wr is enabled the DSE will combine these 2-3
updates into one large write transfer, generally improving performance.
