Subject: media: dt-bindings: media: mediatek: Remove "dma-ranges" property for decoder
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=fa87b0615c19b847b8049da5b67d3d3ec771713c;p=linux.git
media: dt-bindings: media: mediatek: Remove "dma-ranges" property for decoder
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.
