[PATCHv2 23/27] ARM: DRA7: hwmod: Add data for SHA IP

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Lokesh Vutla <lokeshvutla@xxxxxx>

DRA7 SoC contains SHA crypto hardware accelerator. Add hwmod data for
this IP so that it can be utilized by crypto frameworks.
