Subject: [PATCH v2 04/10] iommu/mediatek: mt8195: Add larb_region_msk
Date: Wed, 8 Feb 2023 13:36:37 +0800	[thread overview]
Message-ID: <20230208053643.28249-5-yong.wu@mediatek.com> (raw)
In-Reply-To: <20230208053643.28249-1-yong.wu@mediatek.com>

Add larb_region_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
