crypto: sahara - dma_map_sg can handle chained SG

2015-10-01T13:56:56+00:00

The sahara driver use two dma_map_sg path according to SG are chained
or not.
Since dma_map_sg can handle both case, clean the code with all
references to sg chained.

Thus removing the sahara_sha_unmap_sg function.

Merge branch 'for-4.3/sg' of git://git.kernel.dk/linux-block

2015-09-02T20:22:38+00:00

Pull SG updates from Jens Axboe:
 "This contains a set of scatter-gather related changes/fixes for 4.3:

   - Add support for limited chaining of sg tables even for
     architectures that do not set ARCH_HAS_SG_CHAIN.  From Christoph.

   - Add sg chain support to target_rd.  From Christoph.

   - Fixup open coded sg->page_link in crypto/omap-sham.  From
     Christoph.

   - Fixup open coded crypto ->page_link manipulation.  From Dan.

   - Also from Dan, automated fixup of manual sg_unmark_end()
     manipulations.

   - Also from Dan, automated fixup of open coded sg_phys()
     implementations.

   - From Robert Jarzmik, addition of an sg table splitting helper that
     drivers can use"

* 'for-4.3/sg' of git://git.kernel.dk/linux-block:
  lib: scatterlist: add sg splitting function
  scatterlist: use sg_phys()
  crypto/omap-sham: remove an open coded access to ->page_link
  scatterlist: remove open coded sg_unmark_end instances
  crypto: replace scatterwalk_sg_chain with sg_chain
  target/rd: always chain S/G list
  scatterlist: allow limited chaining without ARCH_HAS_SG_CHAIN

crypto: sahara - Use dmam_alloc_coherent

2015-08-19T14:59:44+00:00

This patch moves the data allocated using dma_alloc_coherent to the
corresponding managed interface. To be compatible with the change,
various gotos are replaced with direct returns and unneeded labels
are dropped.

crypto: sahara - propagate the error on clk_disable_unprepare() failure

2015-06-21T11:59:28+00:00

clk_prepare_enable() may fail, so we should better check its return value
and propagate it in the case of error.

crypto: sahara - fix AES descriptor create

2015-04-08T14:20:06+00:00

The AES implementation still assumes, that the hw_desc[0] has a valid
key as long as no new key needs to be set; consequentialy it always
sets the AES key header for the first descriptor and puts data into
the second one (hw_desc[1]).

Change this to only update the key in the hardware, when a new key is
to be set and use the first descriptor for data otherwise.

for the sahara driver. Use it.

default value is not needed.
