Subject: [PATCH 2/6] remoteproc: sysmon: Add notifications for events
Date: Wed, 19 Feb 2020 18:57:41 -0800	[thread overview]
Message-ID: <1582167465-2549-3-git-send-email-sidgup@codeaurora.org> (raw)
In-Reply-To: <1582167465-2549-1-git-send-email-sidgup@codeaurora.org>

Add notification for other stages of remoteproc boot and shutdown. This
includes adding callback functions for the prepare and unprepare events,
and fleshing out the callback function for start.
