From: Keerthy <[email protected]>
The Security Accelerator Ultra Lite (SA2UL) 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
SA2UL provides support for number of different cryptographic algorithms
including SHA1, SHA256, SHA512, AES, 3DES, and various combinations of
the previous for AEAD use.

It is an old one so not converted to yaml yet though.

Rob, any comments on this one?
I did post the patch for converting omap-rng (the child node) to schema
also.
