| |
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.
