Hi Nicolas,
Add the follwing functions to get a specific device's DMA ranges:
- dev_get_dma_range()
- ofnode_get_dma_range()
- of_get_dma_range()
- fdt_get_dma_range()
They are specially useful in oder to be able validate a physical address space range into a bus's and to convert addresses from and to address spaces.
I'm seeing issues with this patch, with the just posted v2 as well (it's not arrived in my inbox as yet).
I think didn't directly CC you, sorry for that. I'll keep it in mind for the next round.
I get the following linking error when building across a number of devices such as Jetson boards like jetson-tk1, p3450-0000, as well as puma-rk3399, marsboard, udoo, udoo_neo. The error is:
Thanks for having a lookg at this. I've been strugling to test my series against all posible configurations. What are you using catch the regressions? Is something I can run locally?
It's just the list of configs we build for Fedora.

I reproduced it locally, thanks! I'll fit it.
