Subject: [PATCH v3 09/14] crypto: sun8i-ce: handle different error registers
Date: Sun, 21 Jun 2020 19:31:02 +0000 [thread overview]
Message-ID: <1592767867-35982-10-git-send-email-clabbe@baylibre.com> (raw)
In-Reply-To: <1592767867-35982-1-git-send-email-clabbe@baylibre.com>
Error registers are different across SoCs.
This patch handle those difference.
