Subject: [PATCH] crypto: inside-secure/eip93 - fix register definition
Date: Sun,  8 Feb 2026 11:35:53 +0100	[thread overview]
Message-ID: <20260208103602.8168-1-olek2@wp.pl> (raw)

Checked the register definitions with the documentation[1]. Turns out
that the PKTE_INBUF_CNT register has a bad offset. It's used in Direct
Host Mode (DHM). The driver uses Autonomous Ring Mode (ARM), so it
causes no harm.

1. ADSP-SC58x/ADSP-2158x SHARC+ Processor Hardware Reference
Fixes: 9739f5f93b78 ("crypto: eip93 - Add Inside Secure SafeXcel EIP-93 crypto engine support")
