Christian Marangi bbbbd1d149 dt-bindings: crypto: Add Inside Secure SafeXcel EIP-93 crypto engine
Add bindings for the Inside Secure SafeXcel EIP-93 crypto engine.

The IP is present on Airoha SoC and on various Mediatek devices and
other SoC under different names like mtk-eip93 or PKTE.

All the compatible that currently doesn't have any user are defined but
rejected waiting for an actual device that makes use of them.

description: |
The Inside Secure SafeXcel EIP-93 is a cryptographic engine IP block
integrated in varios devices with very different and generic name from
PKTE to simply vendor+EIP93. The real IP under the hood is actually
developed by Inside Secure and given to license to vendors.
The IP block is sold with different model based on what feature are
needed and are identified with the final letter. Each letter correspond
to a specific set of feature and multiple letter reflect the sum of the
feature set.
EIP-93 models:
- EIP-93i: (basic) DES/Triple DES, AES, PRNG, IPsec ESP, SRTP, SHA1
- EIP-93ie: i + SHA224/256, AES-192/256
- EIP-93is: i + SSL/DTLS/DTLS, MD5, ARC4
- EIP-93ies: i + e + s
- EIP-93iw: i + AES-XCB-MAC, AES-CCM
