Thank you Mani!

If possible, I think it would be nice if we could get:
https://lore.kernel.org/linux-pci/20260202145407.503348-1-den@valinux.co.jp/T/#t

Since it is fixing some minor things with the new feature inbound subrange
mappings.

You can probably even squash it if that is preferred.
Although, if you squash merge it,

this commit


commit 72cb5ed2a5c6d87f71a409347f7d3b228fee6bee
Author: Aksh Garg <a-garg7@ti.com>

    PCI: dwc: ep: Add per-PF BAR and inbound ATU mapping support

    (...)
    
    Fixes: 24ede430fa49 ("PCI: designware-ep: Add multiple PFs support for DWC")
    Fixes: cc839bef7727 ("PCI: dwc: ep: Support BAR subrange inbound mapping via Address Match Mode iATU")


has a Fixes that that references the commit that adds subrange inbound
mapping. (So if you squash merge it, you probably want to update the Fixes tag too.)


Kind regards,
Niklas
