-Subject: [PATCH] of/address: Translate 'dma-ranges' for parent nodes
- missing 'dma-ranges'
-
-commit 81db12ee15cb83926e290a8a3654a2dfebc80935 upstream.
-
-'dma-ranges' frequently exists without parent nodes having 'dma-ranges'.
-While this is an error for 'ranges', this is fine because DMA capable
-devices always have a translatable DMA address. Also, with no
-'dma-ranges' at all, the assumption is that DMA addresses are 1:1 with
-no restrictions unless perhaps the device itself has implicit
-restrictions.
