Subject: [PATCH v6 08/10] iommu/mediatek: Extend protect pa alignment value
Date: Fri, 3 Jul 2020 12:41:25 +0800 [thread overview]
Message-ID: <20200703044127.27438-9-chao.hao@mediatek.com> (raw)
In-Reply-To: <20200703044127.27438-1-chao.hao@mediatek.com>
Starting with mt6779, iommu needs to extend to 256 bytes from 128
bytes which can send the max number of data for memory protection
pa alignment. So we can use a separate patch to modify it.
