Please document the new ACPI binding in
Documentation/firmware-guide/acpi/dsd and Cc: the ACPI list so they
can review the binding, same as a DT binding would be reviewed.

The Subject line is wrong. This patch is for net-next. Please read

https://www.kernel.org/doc/html/latest/process/maintainer-netdev.html

and since the merge window is open at the moment, you will need to
wait two weeks before resubmitting.
