The series adds Crypto hardware accelerator support for SA2UL. SA2UL stands for security accelerator ultra lite. The Security Accelerator (SA2_UL) subsystem provides hardware cryptographic acceleration for the following use cases: • Encryption and authentication for secure boot • Encryption and authentication of content in applications requiring DRM (digital rights management) and content/asset protection The device includes one instantiation of SA2_UL named SA2_UL0 SA2UL needs on tx channel and a pair of rx dma channels. This series has dependency on UDMA series. Hence is based on top of: https://patchwork.kernel.org/project/linux-dmaengine/list/?series=114105 The above series adds couple of dmaengine APIs that are used by the sa2ul driver. Hence there is a hard dependency on the above series.
