The new field in struct device 'dma_pfn_offset_map' is used to facilitate
the use of single or multiple pfn offsets between cpu addrs and dma addrs.
It subsumes the role of dev->dma_pfn_offset -- a uniform offset.
The function of_dma_get_range() has been modified to take two additional
arguments:
v4:
Commit "device core: Introduce multiple dma pfn offsets"
-- of_dma_get_range() does not take a dev param but instead
takes two "out" params: map and map_size. We do this so
that the code that parses dma-ranges is separate from
the code that modifies 'dev'. (Nicolas)

Hi Christoph,
a question arouse, is there a real value to dealing with PFNs (as opposed to
real addresses) in the core DMA code/structures? I see that in some cases it
eases interacting with mm, but the overwhelming usage of say,
dev->dma_pfn_offset, involves shifting it.

Sorry, missed one thing.
