Subject: [PATCH] MLK-10036 crypto: caam - add support for DSM with Mega/Fast

mix on

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.
