Subject: [PATCH V7 0/8] Introduce ACPI world to ITS irqchip

The series builds the PCI/MSI domain stack based on initial IORT driver
which is added in first place. As a reference please see IORT spec:
http://infocenter.arm.com/help/topic/com.arm.doc.den0049b/DEN0049B_IO_Remapping_Table.pdf

Tested on Cavium ThunderX server. The patches can be found here:
https://github.com/semihalf-nowicki-tomasz/linux.git (its-acpi-v7)

v6 -> v7
- rebased against irq/irqchip-4.8
- improvements for IORT ID mapping
- call IORT init call from acpi_init() instead of arch_initcall()
- split IORT driver in to two parts: core and ITS/MSI

v5 -> v6
- added locking mechanism for IORT list with domain token
- IORT function name improvements
- extended IORT RID mapping helper
- reworked IORT to be more SMMU friendly
- IORT functions which map RID and find corresponding domain are not
  PCI specific any more (struct pci_dev -> struct device)
- bug fixes

v4 -> v5
- rebased against v4.7-rc1
- drop generic layer and call IORT functions directly
- improve resource abstraction and string formatting

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 (8):
  ACPI: I/O Remapping Table (IORT) initial support
  ACPI: Add new IORT functions to support MSI domain handling
  PCI/MSI: Setup MSI domain on a per-device basis using IORT ACPI table
  irqchip/gicv3-its: Cleanup for ITS domain initialization
  irqchip/gicv3-its: Refactor ITS DT init code to prepare for ACPI
  irqchip/gicv3-its: Probe ITS in the ACPI way
  irqchip/gicv3-its: Factor out code that might be reused for ACPI
  irqchip/gicv3-its: Use MADT ITS subtable to do PCI/MSI domain
    initialization
