Hi Hanjun:
	This patch set works fine on my Hisilicon D05 board.
Feel free to add
	Tested-by: Majun <[email-masked]>

> v4 -> v5:
> 	- Add mbigen support back with tested on with Agustin's patchset,
> 	  and it's a good example of how ACPI platform MSI works
> 	- rebased on top of lastest Linus tree (commit 52bce91 splice: reinstate SIGPIPE/EPIPE handling)
> 
> v3 -> v4:
>         - Drop mbi-gen patches to just submit platform msi support because
>           will rebase mbi-gen patches on top of Agustin's patchset, and discusion
>           is going there.
>         - Add a patch to support device topology such as NC(named componant, paltform device)
>           ->SMMU->ITS which suggested by Lorenzo;
>         - rebased on top of Lorenzo's v9 of ACPI IORT ARM SMMU support;
>         - rebased on top of 4.9-rc7
> 
> v2 -> v3:
>         - Drop RFC tag
>         - Rebase against v4.9-rc2 and Lorenzo's v6 of ACPI IORT ARM SMMU support [1]
>         - Add 3 cleanup patches (patch 1, 2, 3)
>         - Drop arch_init call patch from last version
>         - Introduce a callback for platform device to set msi domain
>         - Introduce a new API to get paltform device's domain instead of
>           reusing the PCI one in previous version
>         - Add a patch to rework iort_node_get_id()
> 
> [1]: http://www.mail-archive.com/linux-kernel at vger.kernel.org/msg1251993.html
> 
> v1 -> v2:
>         - Fix the bug of if multi Interrupt() resoures in single _PRS,
>           we need to calculate all the irq numbers (I missed it in previous
>           version);
>         - Rebased on Marc's irq/irqchip-4.9 branch and Lorenzo's v5
>           SMMU patches (also Robin's SMMu patches)
>         - Add patch irqchip: mbigen: promote mbigen init.
> 
> With platform msi support landed in the kernel, and the introduction
> of IORT for GICv3 ITS (PCI MSI) and SMMU, the framework for platform msi
> is ready, this patch set add few patches to enable the ACPI platform
> msi support.
> 
> For platform device connecting to ITS on arm platform, we have IORT
> table with the named componant node to describe the mappings of paltform
> device and ITS, so we can retrieve the dev id and find its parent
> irqdomain (ITS) from IORT table (simlar with the ACPI ITS support).
> 
> The fisrt 3 patches are cleanups;
> 
> Patch 4,5 are refactoring its_pmsi_prepare() for both DT and ACPI
> then retrieve the dev id from iort;
> 
> Patch 6,7 to create platform msi domain to ACPI case which scanned
> the MADT table;
> 
> Patch 8,9,10,11 to setup the msi domain for platform device based
> on IORT table.
> 
> Patch 12,13,14 convert dt based mbigen driver to support ACPI.
> 
> Teasted on Hisilicon D03/D05.
