This series includes only the refactoring commits from [1]. The batching
related changes were dropped since they are no longer relevant (batching
support in crypto_engine was retired in [2]).

This series includes various small cleanups and refactoring:
- move request-specific skcipher and hash data to request context,
  eliminating the need to allocate extra memory in the digest path
- make the hashing code more clear and modular
- reduce a bit of boilerplate/duplicated code

Changes in v3:
   - dropped ____cacheline_aligned attributes from buffers used for
     to-device DMA only
   - set up proper alignment for ahash reqctx, in order to allow from-device DMA
     into reqctx buffer:
      * increased ahash reqsize by CRYPTO_DMA_PADDING
      * added __aligned(CRYPTO_DMA_ALIGN) attribute for the 'result' buffer
      * converted all ahash_request_ctx_dma() calls to ahash_request_ctx_dma()

Changes in v2:
   - fixed [-Wunused-but-set-variable] warning reported by kernel test robot

[2] c470ffa6f486 ("crypto: engine - remove request batching support")

Ovidiu Panait (9):
  crypto: sun8i-ce - remove channel timeout field
  crypto: sun8i-ce - remove boilerplate in sun8i_ce_hash_digest()
  crypto: sun8i-ce - remove unnecessary __maybe_unused annotations
  crypto: sun8i-ce - add a new function for dumping task descriptors
  crypto: sun8i-ce - move bounce_iv and backup_iv to request context
  crypto: sun8i-ce - fold sun8i_ce_cipher_run() into
    sun8i_ce_cipher_do_one()
  crypto: sun8i-ce - pass task descriptor to cipher prepare/unprepare
  crypto: sun8i-ce - save hash buffers and dma info to request context
  crytpo: sun8i-ce - factor out prepare/unprepare from
    sun8i_ce_hash_run()
