Previous commit "removed redundant locking" introduced
a bug in handling backlog.
In certain cases, when async request complete callback will
call complete() on -EINPROGRESS code, it will cause uncompleted requests.
It does not happen in implementation similar to crypto test manager,
but it will happen in implementation similar to dm-crypt.
Backlog needs to be checked before dequeuing next request.Signed-off-by: Dmitry Kasatkin

If scatterlist have more than one entry, current driver uses

According to the Herbert Xu, client may not always call
crypto_ahash_final().In the case of error in hash calculation resources will be
automatically cleaned up.But if no hash calculation error happens and client will not call
crypto_ahash_final() at all, then internal buffer will not be freed,
and clocks will not be disabled.This patch provides support for atomic crypto_ahash_update() call.
Clocks are now enabled and disabled per update request.Data buffer is now allocated as a part of request context.
Client is obligated to free it with crypto_free_ahash().Signed-off-by: Dmitry Kasatkin

Introduces DMA error handling.
DMA error is returned as a result code of the hash request.
Clients needs to handle error codes and may repeat hash calculation attempt.Also in the case of DMA error, SHAM module is set to be re-initialized again.
It significantly improves stability against possible HW failures.Signed-off-by: Dmitry Kasatkin

05 Nov, 2010

On certain VIA chipsets AES-CBC requires the input/output to be
a multiple of 64 bytes. We had a workaround for this but it was
buggy as it sent the whole input for processing when it is meant
to only send the initial number of blocks which makes the rest
a multiple of 64 bytes.As expected this causes memory corruption whenever the workaround
kicks in.Reported-by: Phil Sutter

DMA is set to use burst mode also for source channel. It should
descrease memory bandwidth needs.DMA synchronization is set to use prefetch mechanism. SHAM block is behind
L4 bus and it doesn't have fifo. SHAM block is stalling as long as the new
data is available. It takes time to fetch data from memory and transfer it
via L4 bus. With prefetch enabled, data is waiting in DMA fifo and SHAM block
receives new data block faster.
This increases SHA processing speed up to 30 percent depending on the
bus / memory load.Signed-off-by: Samu Onkalo

of_device is just an alias for platform_device, so remove it entirely. Also
replace to_of_device() with to_platform_device() and update comment blocks.This patch was initially generated from the following semantic patch, and then
edited by hand to pick up the bits that coccinelle didn't catch.@@
