Hi,
This patch series fixes a DT based address translation (translations
using the ranges property).
The issue is present with a ranges property made of a 3 cells child
address, a 3 cells parent address and a 2 cells child size.
This can happen with the recent addition of of_pci_prop_ranges() in
commit 407d1a51921e ("PCI: Create device tree node for bridge")
The issue description is fully described in the first patch commit log.
In this series,
- The first patch fixes the issue.
- The second patch avoids duplicated code.
- The third patch adds unit tests related address translations.
I previously sent the first patch alone:
https://lore.kernel.org/linux-kernel/20231003065236.121987-1-herve.codina@xxxxxxxxxxx/
This series v2 has to be considered as the next iteration based on the
review done on my previous patch sent alone.
Best regards,
Hervé
