From fa87b0615c19b847b8049da5b67d3d3ec771713c Mon Sep 17 00:00:00 2001 From: Allen-KH Cheng Date: Fri, 3 Mar 2023 01:38:38 +0000 Subject: [PATCH] media: dt-bindings: media: mediatek: Remove "dma-ranges" property for decoder MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Because the decoder nodes already make use of the iommus property to configure the IOMMU for address translations, having a dma-ranges property makes no sense. In fact, after commit f1ad5338a4d5 ("of: Fix "dma-ranges" handling for bus controllers"), having a dma-ranges property causes IOMMU faults. Remove the dma-ranges property and update the example.
