      crypto: caam - fix DECO RSR polling · 8f1da7b9
      Horia Geanta authored
      RSR (Request Source Register) is not used when
      virtualization is disabled, thus don't poll for Valid bit.
      
      Besides this, if used, timeout has to be reinitialized.

      Chen Gang authored
      'DEV_QCE' needs both HAS_DMA and HAS_IOMEM, so let it depend on them.

      crypto: caam - set DK (Decrypt Key) bit only for AES accelerator · a60384df
      Horia Geanta authored
      AES currently shares descriptor creation functions with DES and 3DES.
      DK bit is set in all cases, however it is valid only for
      the AES accelerator.

      crypto: testmgr - avoid DMA mapping from text, rodata, stack · 29b77e5d
      Horia Geanta authored
      With DMA_API_DEBUG set, following warnings are emitted
      (tested on CAAM accelerator):
      DMA-API: device driver maps memory from kernel text or rodata
      DMA-API: device driver maps memory from stack
      and the culprits are:
      -key in __test_aead and __test_hash
      -result in __test_hash
      
      MAX_KEYLEN is changed to accommodate maximum key length from
      existing test vectors in crypto/testmgr.h (131 bytes) and rounded.

      crypto: ccp - Base AXI DMA cache settings on device tree · 126ae9ad
      Tom Lendacky authored
      The default cache operations for ARM64 were changed during 3.15.
      To use coherent operations a "dma-coherent" device tree property
      is required.  If that property is not present in the device tree
      node then the non-coherent operations are assigned for the device.
      
      Add support to the ccp driver to assign the AXI DMA cache settings
      based on whether the "dma-coherent" property is present in the device
      node.  If present, use settings that work with the caches.  If not
      present, use settings that do not look at the caches.
