Subject: [PATCH v5 0/4] Add Aspeed ACRY driver for hardware acceleration

Aspeed ACRY engine is designed to accelerate the throughput of
ECDSA/RSA signature and verification.

These patches aim to add Aspeed ACRY RSA driver support.
This driver also pass the run-time self tests that take place at
algorithm registration on both big-endian/little-endian system
in AST2600 evaluation board .

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
- CONFIG_CPU_BIG_ENDIAN=y

Change since v4:
- Remove GFP_DMA flag since it's unnecessary.

Change since v3:
- Revise aspeed,ast2600-ahbc.yaml dt-bindings description.

Change since v2:
- Fix format and uninitialized warning.
- Revise binding description.

Change since v1:
- Fix dt-bindings description.
- Refine the Makefile which has been addressed.

Neal Liu (4):
  crypto: aspeed: Add ACRY RSA driver
  ARM: dts: aspeed: Add ACRY/AHBC device controller node
  dt-bindings: crypto: add documentation for Aspeed ACRY
  dt-bindings: bus: add documentation for Aspeed AHBC
