Looks v7 works fine on D05, together with Lorenzo's
fix([v2] ACPI/IORT: Fix iort_node_get_id() mapping entries indexing) and
Agustin's patchset of "v9 irqchip: qcom: Add IRQ combiner driver".

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:

Thanks!

I didn't test PCIe it's good to know it's working, thanks for testing
and let me know.
