slightly ping.
I think the series can be re-organized as 3 patches:

ACPI: LoongArch: Add acpi_arch_[late]_init()
includes Patch-1/4 in this series roughly.

ACPI: LoongArch: Add IOVT device entry table scanning
includes Patch-3/5/6/7 in this series roughly.

ACPI: LoongArch: Add ACPI_IOVT config options
includes Patch-2/8 in this series roughly.
Waiting the response from others, will do this if there is no disagreement.
