Use ablkcipher_request_cast() instead of open-coding it.

crypto: picoxcell - set [src|dst]_nents and nents as signed int

2015-11-23T12:55:55+00:00

The unsigned int variables [src|dst]_nents and nents can be assigned
signed value (-EINVAL) from sg_nents_for_len().
Furthermore they are used only by dma_map_sg and dma_unmap_sg which wait
for an signed int, so they must be set as int.

crypto: picoxcell - check return value of sg_nents_for_len

2015-11-17T14:00:37+00:00

The sg_nents_for_len() function could fail, this patch add a check for
its return value.
In the same time, we remove sg_count() as it is used as an alias of
sg_nents_for_len.

crypto: picoxcell - Fix module autoload for OF platform driver

2015-09-21T14:00:36+00:00

This platform driver has a OF device ID table but the OF module
alias information is not created so module autoloading won't work.

crypto: aead - Remove CRYPTO_ALG_AEAD_NEW flag

2015-08-17T08:53:53+00:00

This patch removes the CRYPTO_ALG_AEAD_NEW flag now that everyone
has been converted.

crypto: picoxcell - Convert to new AEAD interface

2015-08-04T12:45:33+00:00

This patch converts picoxcell to the new AEAD interface.  IV
generation has been removed since it's equivalent to a software
implementation.

As picoxcell cannot handle SG lists longer than 16 elements,
this patch has made the software fallback mandatory.  If an SG
list comes in that exceeds the limit, we will simply use the
fallback.

crypto: picoxcell - Update to the current clk API

2015-06-21T11:59:22+00:00

The picoXcell hardware crypto accelerator driver was using an
older version of the clk framework, and not (un)preparing the
clock before enabling/disabling it.  This change uses the handy
clk_prepare_enable function to interact with the current clk
framework correctly.

crypto: picoxcell - Clamp AEAD SG list by input length

2015-06-12T14:45:09+00:00

Currently the driver assumes that the SG list contains exactly
the number of bytes required.  This assumption is incorrect.

Up until now this has been harmless.  However with the new AEAD
interface this now breaks as the AD SG list contains more bytes
than just the AD.

This patch fixes this by always clamping the AD SG list by the
specified AD length.

crypto: picoxcell - Make use of sg_nents_for_len

2015-06-12T14:45:08+00:00

This patch makes use of the new sg_nents_for_len helper to replace
the custom sg_count function.
