From 6970cadb216cef7951bc915a841123d0967e08bc Mon Sep 17 00:00:00 2001 From: =?utf8?q?N=C3=ADcolas=20F=2E=20R=2E=20A=2E=20Prado?= Date: Thu, 1 Jun 2023 16:32:21 -0400 Subject: [PATCH] arm64: dts: mediatek: mt8192: Add missing dma-ranges to soc node MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit In the series "Adjust the dma-ranges for MTK IOMMU", the mtk-iommu driver was adapted to separate the iova range based on the larb used, and a dma-ranges property was added to the soc node in the devicetree of the affected SoCs allowing the whole 16GB iova range to be used. Except that for mt8192, there was no patch adding dma-ranges. Add the missing dma-ranges property to the soc node like was done for mt8195 and mt8186. This fixes the usage of the vcodec, which would otherwise trigger iommu faults. Signed-off-by: Nícolas F. R. A.
