It will be implementation specific. The ACPI spec folk have gathered some of the range of
ways people are putting this together. We should take that into account with the binding,
otherwise we end up with a 'v1' and 'v2' of the binding and have to support both.

There is a 'Beta 2' of that ACPI document. It should appear on the website at some point.
Qualcomm should have this somewhere, its called 'DEN0085_RAS_ACPI_1.0_RELEASE_BETA2.pdf.
