This patch series adds kernel driver support for StarFive JH7110 crypto
engine. The first patch adds Documentations for the device and Patch 2
adds device probe and DMA init for the module. Patch 3 adds crypto and
DMA dts node for VisionFive 2 board. Patch 4 adds hash/hmac support to
the module.

Patch 3 needs to be applied on top of:
https://lore.kernel.org/lkml/20230424135409.6648-3-xingyu.wu@starfivetech.com/

Patch 4 needs to be applied on top of:
https://lore.kernel.org/linux-crypto/ZEEOXIHwqKblKfBJ@gondor.apana.org.au/T/#u

Changes v7->v8
- Enable COMPILE_TEST in Kconfig (Herbert)
- Fix compile_test warning on 'long unsigned int' to 'unsigned int'
  conversion (Herbert)

Changes v6->v7
- Remove NULL assignment as struct is kzalloc()-ed (Christophe)
- Do clk_disable_unprepare and assert reset if probe failed (Christophe)
- Remove unnecessary null pointer check (Christophe)
- Update module name in Kconfig description (Christophe)

Changes v5->v6
- Remove set_crypt in export as request will have been created by
  init/updated calls (Herbert)
- Use new helper to set statesize of crypto_ahash (Herbert)
- Use crypto_ahash_blocksize instead of crypto_ahash_tfm (Herbert)
- Switch to init_tfm/exit_tfm instead of cra_init/cra_exit (Herbert)

Changes v4->v5
- Schedule tasklet from IRQ handler instead of using completion to sync
  events (Herbert)

Changes v3->v4:
- Use fallback for non-aligned cases as hardware doesn't support
  hashing piece-meal (Herbert)
- Use ahash_request_set_* helpers to update members of ahash_request
  (Herbert)
- Set callbacks for async fallback (Herbert)
- Remove completion variable and use dma_callback to do the rest of
  processing instead. (Herbert)

Changes v2->v3:
- Only implement digest and use fallback for other ops (Herbert)
- Use interrupt instead of polling for hash complete (Herbert)
- Remove manual data copy from out-of-bound memory location as it will
  be handled by DMA API. (Christoph & Herbert)

Changes v1->v2:
- Fixed yaml filename and format (Krzysztof)
- Removed unnecessary property names in yaml (Krzysztof)
- Moved of_device_id table close to usage (Krzysztof)
- Use dev_err_probe for error returns (Krzysztof)
- Dropped redundant readl and writel wrappers (Krzysztof)
- Updated commit signed offs (Conor)
- Dropped redundant node in dts, module set to on in dtsi (Conor)

Jia Jie Ho (4):
  dt-bindings: crypto: Add StarFive crypto module
  crypto: starfive - Add crypto engine support
  riscv: dts: starfive: Add crypto and DMA node for VisionFive 2
  crypto: starfive - Add hash and HMAC support

OK, I've dropped it.
