There is a second ACPI _DSD document from the UEFI Forum that details how _DSD style tables can be nested, creating a tree of similarly formatted tables. This document is linked from acpi_device.h. In order to support this the device property interface needs to be more flexible and build up a tree of properties to write all entries at once instead of writing each entry as it is generated. In the end this is a more flexible solution that can support drivers that need child tables like the DA7219 codec, while only requiring minor changes to the existing drivers that use the device property interface. This was tested on reef (apollolake) and chell (skylake) boards to ensure that there was no change in the generated SSDT AML.
