| 2025-04-10 | crypto: tegra - Use separate buffer for setkey | Akhil R | |
| [ Upstream commit bcfc8fc53f3acb3213fb9d28675244aa4ce208e0 ] The buffer which sends the commands to host1x was shared for all tasks in the engine. This causes a problem with the setkey() function as it gets called asynchronous to the crypto engine queue. Modifying the same cmdbuf in setkey() will corrupt the ongoing host1x task and in turn break the encryption/decryption operation. Hence use a separate cmdbuf for setkey().

| 2024-04-12 | crypto: tegra - Add Tegra Security Engine driver | Akhil R | |
| Add support for Tegra Security Engine which can accelerate various crypto algorithms. The Engine has two separate instances within for AES and HASH algorithms respectively. The driver registers two crypto engines - one for AES and another for HASH algorithms and these operate independently and both uses the host1x bus. Additionally, it provides hardware-assisted key protection for up to 15 symmetric keys which it can use for the cipher operations.
