This patch update of_dma_configure() API to calculate the
masks (dma_mask and coherent_dma_mask) based on the dma-range
values set in DT for the device. Also limit the mask to lower
of the default mask and mask calculated.

Applied with Catalin's reviewed-by to pci/iommu for v4.1, thanks!
Bjorn,

Could you point me to this? I didn't see it on pci/iommu of your repo below.

I had applied it to my local branch, but not pushed it to kernel.org.
I applied it along with the "get DMA configuration from parent device"
series to pci/murali-v8 and pushed it for build testing.
