Subject: [PATCH 2/3] sbsa_gwdt: Use max_hw_heartbeat_ms instead of max_timeout
Date: Tue, 31 May 2016 14:08:09 +0800 [thread overview]
Message-ID: <1464674890-10512-3-git-send-email-fu.wei@linaro.org> (raw)
In-Reply-To: <1464674890-10512-1-git-send-email-fu.wei@linaro.org>
From: Pratyush Anand <panand@redhat.com>
Using max_hw_heartbeat_ms instead of max_timeout gives the flexibility to
achieve higher user "timeout". Therefore, use this new infrastructure.
