Subject: [PATCH v5 06/11] iommu/mediatek: mt8195: Add iova_region_larb_msk
Date: Tue, 7 Mar 2023 10:35:02 +0800 [thread overview]
Message-ID: <20230307023507.13306-7-yong.wu@mediatek.com> (raw)
In-Reply-To: <20230307023507.13306-1-yong.wu@mediatek.com>
Add iova_region_larb_msk for mt8195. We separate the 16GB iova regions
by each device's larbid/portid.
Refer to include/dt-bindings/memory/mt8195-memory-port.h
