Subject: [PATCH 14/21] iommu/mediatek: Add single domain
Date: Sat, 11 Jul 2020 14:48:39 +0800	[thread overview]
Message-ID: <20200711064846.16007-15-yong.wu@mediatek.com> (raw)
In-Reply-To: <20200711064846.16007-1-yong.wu@mediatek.com>

Defaultly the iova range is 0-4G. here we add a single-domain(0-4G)
for the previous SoC. this also is a preparing patch for supporting
multi-domains.
