[PATCH] arm64: dts: ti: k3-j721s2-main: Enable crypto accelerator

From: Jayesh Choudhary
Date: Tue Jun 28 2022 - 01:45:36 EST


Add the node for SA2UL for supporting hardware crypto algorithms,
including SHA1, SHA256, SHA512, AES, 3DES and AEAD suites.

There is a dependency of this patch on a dmaengine patch:
<https://lore.kernel.org/all/20220628050232.331956-1-j-choudhary@xxxxxx/>
This patch adds the PSIL threads for main domain SA2UL.

Without the above patch, dma-controller fails to get the channel
and tcrypt module does software crypto. But it does not break boot
since its runtime and not compile-time.

Testing log: <https://gist.github.com/Jayesh2000/e429c78a545809602e6473886a2a6ae4>
