Gentle ping on these patch series, thanks.

> 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.
> 
> The patch series are tested on both AST2500 & AST2600 evaluation boards.

> 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 v6:
> - Refine debug print.
> - Change aspeed_sg_list struct memeber's type to __le32.

> Change since v5:
> - Re-define HACE clock define to fix breaking ABI.

> Change since v4:
> - Add AST2500 clock definition & dts node.
> - Add software fallback for handling corner cases.
> - Fix copy wrong key length.
> 
> Change since v3:
> - Use dmam_alloc_coherent() instead to manage dma_alloc_coherent().
