Subject: [PATCH V4 0/7] Introduce ACPI world to ITS irqchip

The following git branch contains submitted patches along with
the useful patches from the test point of view (mainly ACPI ARM64 PCI support).
https://github.com/semihalf-nowicki-tomasz/linux.git (its-acpi-v4)

Series has been tested on Cavium ThunderX and Qualcomm QDF2xxx server.

v3 -> v4
- rebased against v4.5
- add ACPI support for IRQ domain handling on a per-device basis
- reorder domain setup step
- improve error handling
- code style improvements

v2 -> v3
- rebased on top of 4.4
- fixes and improvements for redistributor init via GICC structures
- fixes as per kbuild reports

v1 -> v2
- rebased on top of 4.4-rc4
- use pci_msi_domain_get_msi_rid for requester ID to device ID translation

Tomasz Nowicki (7):
  acpi, pci: Setup MSI domain on a per-devices basis.
  irqchip, GICv3, ITS: Cleanup for ITS domain initialization.
  irqchip, GICv3, ITS: Refator ITS DT init code to prepare for ACPI.
  ARM64, ACPI, PCI: I/O Remapping Table (IORT) initial support.
  irqchip, gicv3, its: Probe ITS in the ACPI way.
  its, pci, msi: Factor out code that might be reused for ACPI.
  acpi, gicv3, its: Use MADT ITS subtable to do PCI/MSI domain
    initialization.
