Subject: [PATCH v3 00/12] PCI: mvebu: subsystem ids, AER and INTx

This patch series extends pci-bridge-emul.c driver to emulate PCI Subsystem
Vendor ID capability and PCIe extended capabilities. And then implement
in pci-mvebu.c driver support for PCI Subsystem Vendor IDs, PCIe AER
registers, support for legacy INTx interrupts, configuration for X1/X4
mode and usage of new PCI child_ops API.

Changes in v3:
* add Marek's Reviewed-by for first two patches
* split comments from "PCI: mvebu: Implement support for legacy INTx
  interrupts" patch into separate patch

Changes in v2:
* use static structures for INTx interrupts
* remove INTx domain after unregistering INTx handler

Pali Rohár (10):
  PCI: pci-bridge-emul: Add support for PCI Bridge Subsystem Vendor ID
    capability
  dt-bindings: PCI: mvebu: Add num-lanes property
  PCI: mvebu: Correctly configure x1/x4 mode
  PCI: mvebu: Add support for PCI Bridge Subsystem Vendor ID on emulated
    bridge
  PCI: mvebu: Add support for Advanced Error Reporting registers on
    emulated bridge
  PCI: mvebu: Use child_ops API
  dt-bindings: PCI: mvebu: Update information about intx interrupts
  PCI: mvebu: Fix macro names and comments about legacy interrupts
  PCI: mvebu: Implement support for legacy INTx interrupts
  ARM: dts: armada-385.dtsi: Add definitions for PCIe legacy INTx
    interrupts

Russell King (2):
  PCI: pci-bridge-emul: Re-arrange register tests
  PCI: pci-bridge-emul: Add support for PCIe extended capabilities
