Subject[PATCH v3 0/4] PCI: X-Gene: Add APM X-Gene v1 MSI/MSIX termination driver
Date
This patch set adds MSI/MSIX termination driver support for APM X-Gene v1 SoC.
APM X-Gene v1 SoC supports its own implementation of MSI, which is not compliant
to GIC V2M specification for MSI Termination.

There is single MSI block in X-Gene v1 SOC which serves all 5 PCIe ports. This MSI
block supports 2688 MSI termination ports coalesced into 16 physical HW IRQ lines
and shared across all 5 PCIe ports.

v3 changes:
1. Implement MSI support using PCI MSI IRQ domain
2. Only use msi_controller to store IRQ domain
v2 changes:
1. Use msi_controller structure
2. Remove arch hooks arch_teardown_msi_irqs and arch_setup_msi_irqs
