Subject: [PATCH V3 01/12] dmaengine/dw_dmac: Hibernation support in dw_dmac
Date: Wed, 1 Feb 2012 16:12:17 +0530	[thread overview]
Message-ID: <91f435464b40009113ddc3d2287f10d81e498654.1328091915.git.viresh.kumar@st.com> (raw)
In-Reply-To: <cover.1328091915.git.viresh.kumar@st.com>

From: Rajeev KUMAR <rajeev-dlh.kumar@st.com>

The suspend and resume implementation is through dev_pm_ops in dmac. So
in order to support hibernation, freeze, thaw, restore and poweroff
features are required.
