SubjectRe: [PATCH v5 00/14] ACPI platform MSI support and its example mbigen
From
Date
Hi Hanjun:
This patch set works fine on my Hisilicon D05 board.
Feel free to add
Tested-by: Majun <majun258@huawei.com>

> - Add a patch to rework iort_node_get_id()

> For platform device connecting to ITS on arm platform, we have IORT

>
> 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.
