Thanks for your feedback so far.


Changes in v3:

- Rework the macros which retrieve larb/port ID to improve human readability
- Link to v2: https://lore.kernel.org/r/20221001-iommu-support-v2-0-dbfef2eeebc9@xxxxxxxxxxxx

Changes in v2:
- Rebase.

- Rename to int_id_port_width for more detail.
- Fix typo.
- Set banks_enable and banks_num in mt8365_data to fix kernel panic at boot.
