Hi Hanjun:
This patch set works fine on my Hisilicon D05 board.
Feel free to add

> Patch 4,5 are refactoring its_pmsi_prepare() for both DT and ACPI

> Patch 6,7 to create platform msi domain to ACPI case which scanned

> Patch 8,9,10,11 to setup the msi domain for platform device based

> Patch 12,13,14 convert dt based mbigen driver to support ACPI.
