I tested this patch set on the Hisilicon D05 board with these patches:

  [1] Agustin's V9 IRQ combiner driver patch set
      https://patchwork.kernel.org/patch/9474751/

  [2] Lorenzo's v2 iort_node_get_id fix patch
      https://patchwork.kernel.org/patch/9507041/

The branch is at https://github.com/hisilicon/linux-hisi/tree/topic-acpi-mbigen.

The integrated XGE, SAS and PCIe controller works fine.
So with this patch set:

Tested-by: Wei Xu <xuwei5@...ilicon.com>

Thanks!

Best Regards,
