Hi Christoph and Nicolas,
Did a version of that series ever get send out? I am coming into the
conversation late but I am running into an issue with the Raspberry Pi 4
not booting on linux-next, which appears to be due to this patch now in
mainline as commit d9765e41d8e9 ("dma-pool: do not allocate pool memory
from CMA") combined with
https://lore.kernel.org/lkml/20200725014529.1143208-2-jiaxun.yang@flygoat.com/

I am unsure if it is related to the issue that Amit is having or
if that makes sense at all but I can reliably reproduce it.
v5.8-rc1: OK
v5.8-rc1 + d9765e41d8e9e: OK
v5.8-rc1 + "of_address: Add bus type match for pci ranges parser": OK
v5.8-rc1 + both: BROKEN
I wanted to test the series to see if this fixes anything. If you would
prefer a different thread for this or further information, please let
me know.
Cheers,
Nathan
