+From 1ffdfbcd42dbb87f2841e45c0719a3fbcb2fe926 Mon Sep 17 00:00:00 2001

+Subject: [PATCH] MLK-10036 crypto: caam - add support for DSM with Mega/Fast
+ mix on
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This patch allows CAAM to be enabled as a wakeup source for the
+Mega/Fast mix domain. If CAAM is enabled as a wakeup source, it
+will continue to be powered on across Deep Sleep Mode (DSM). This
+allows CAAM to be functional after the system resumes from DSM.
