Subject: [PATCH 0/2] PCI: endpoint: BAR subrange mapping support

This series proposes support for mapping subranges within a PCIe endpoint
BAR and enables controllers to program inbound address translation for
those subranges.

The first patch introduces generic BAR subrange mapping support in the
PCI endpoint core. The second patch adds an implementation for the
DesignWare PCIe endpoint controller using Address Match Mode IB iATU.

This series is a spin-off from a larger RFC series posted earlier:
https://lore.kernel.org/all/20251217151609.3162665-4-den@valinux.co.jp/

Base:
  git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci.git
  branch: controller/dwc
  commit: 68ac85fb42cf ("PCI: dwc: Use cfg0_base as iMSI-RX target address
                         to support 32-bit MSI devices")

Thank you for reviewing,
