Subject: [PATCHv4 1/7] dt-bindings: crypto: Add TI SA2UL crypto accelerator documentation
Date: Mon, 15 Jun 2020 10:14:46 +0300 [thread overview]
Message-ID: <20200615071452.25141-2-t-kristo@ti.com> (raw)
In-Reply-To: <20200615071452.25141-1-t-kristo@ti.com>
From: Keerthy <j-keerthy@ti.com>
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.
