Subject: [PATCH v2 0/5] Add Aspeed crypto driver for hardware acceleration

Aspeed Hash and Crypto Engine (HACE) is designed to accelerate the
throughput of hash data digest, encryption and decryption.

These patches aim to add Aspeed hash & crypto driver support.
The hash & crypto driver also pass the run-time self tests that
take place at algorithm registration.

Tested-by below configs:
- CONFIG_CRYPTO_MANAGER_DISABLE_TESTS is not set
- CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y
- CONFIG_DMA_API_DEBUG=y
- CONFIG_DMA_API_DEBUG_SG=y

Change since v1:
- Add more error handlers, including DMA memory allocate/free, DMA
  map/unmap, clock enable/disable, etc.
- Fix check dma_map error for config DMA_API_DEBUG
- Fix dt-binding doc & dts node naming


Neal Liu (5):
  crypto: aspeed: Add HACE hash driver
  dt-bindings: clock: Add AST2600 HACE reset definition
  ARM: dts: aspeed: Add HACE device controller node
  dt-bindings: crypto: add documentation for aspeed hace
  crypto: aspeed: add HACE crypto driver
