Subject: [PATCH 01/10] dt-bindings: media: mediatek,vcodec: Remove dma-ranges property
Date: Fri, 13 Jan 2023 14:01:24 +0800	[thread overview]
Message-ID: <20230113060133.9394-2-yong.wu@mediatek.com> (raw)
In-Reply-To: <20230113060133.9394-1-yong.wu@mediatek.com>

MediaTek iommu has already controlled the masters' iova ranges by the
master's larb/port id. then the dma-ranges property is unnecessary for
the master's node. the master is vcodec here.
