Subject: [Patch v15 3/5] iommu/arm-smmu: Add the device_link between masters and smmu
Date: Mon, 27 Aug 2018 16:25:49 +0530 [thread overview]
Message-ID: <20180827105551.16346-4-vivek.gautam@codeaurora.org> (raw)
In-Reply-To: <20180827105551.16346-1-vivek.gautam-sgV2jX0FEOL9JmXXK+q4OQ@public.gmane.org>
From: Sricharan R <sricharan@codeaurora.org>
Finally add the device link between the master device and
smmu, so that the smmu gets runtime enabled/disabled only when the
master needs it. This is done from add_device callback which gets
called once when the master is added to the smmu.
