Subject: [PATCH v2 03/19] iommu/mediatek: Extend larb_remap to larb_remap[2]
Date: Sun, 5 Jan 2020 18:45:07 +0800 [thread overview]
Message-ID: <20200105104523.31006-4-chao.hao@mediatek.com> (raw)
In-Reply-To: <20200105104523.31006-1-chao.hao@mediatek.com>
For more than one IOMMUs, they are corresponding to different
smi_larb id, so we need to extend larb_remap to larb_remap[2]
to distinguish it by index.
