Merge tag 'dt-dma-properties-for-arm' of git://git.kernel.org/pub/scm/linux/kernel/git/ssantosh/linux-keystone into devel-stable
DT support for 'dma-ranges'and 'dma-coherent' properties with ARM updates
- The 'dma-ranges' helps to take care of few DMAable system memory
restrictions by use of dma_pfn_offset which is maintained per
device. Arch code then uses it for dma address translations for such
cases. We update the dma_pfn_offset accordingly during DT the device
creation process.
- The 'dma-coherent' property is used to setup arch's coherent dma_ops.
