Hi Aaro and Tony,
omap1 is the last arm platform implementing __arch_pfn_to_dma and
__arch_dma_to_pfn. Any chance you could help converting them to
use the dma pfn offset in struct device [1] instead?
Thanks,
Christoph
p1] which we are also reworking to support multiple ranges, but I
can help with fixing that up easily

Sounds like a plan, however I don't have currently access to my omap1
devices and won't for about a month. Aaro care to look at this?

Seems arch/arm/mach-keystone/keystone.c can be used as reference.
