Merge tag 'dt-dma-properties-for-arm' of git://git.kernel.org/pub/scm/linux/kernel/git/ssantosh/linux-keystone into depends/dma-ranges 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. * tag 'dt-dma-properties-for-arm' of git://git.kernel.org/pub/scm/linux/kernel/git/ssantosh/linux-keystone: ARM: dma: use phys_addr_t in __dma_page_[cpu_to_dev/dev_to_cpu] ARM: dma: implement set_arch_dma_coherent_ops() ARM: dma: Use dma_pfn_offset for dma address translation of: configure the platform device dma parameters of: introduce of_dma_is_coherent() helper of: introduce of_dma_get_range() helper device: introduce per device dma_pfn_offset Signed-off-by: Arnd Bergmann <arnd@arndb.de>
