[PATCH v4 0/5] Add Tegra Security Engine driver

From: Akhil R
Date: Wed Jan 24 2024 - 03:39:26 EST


Add support for Tegra Security Engine which can accelerates 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.

v3->v4:
* Remove unused header in bindings doc.
* Update commit message in host1x change.
* Fix test bot warning.
v2->v3:
* Update compatible in driver and device trees.
* Remove extra new lines and symbols in binding doc.
v1->v2:
* Update probe errors with 'dev_err_probe'.
* Clean up function prototypes and redundant prints.
* Remove readl/writel wrappers.
* Fix test bot warnings.
