But have we explored or investigated what it takes to rewrite ACPI f/w to just use standard methods ? Does it require more firmware changes or new firmware entities or impossible at any cost ? For me that is more important than just getting this one on DT. Because if you take that path, we will have to keep doing that, with loads of unnecessary drivers if they are not shared with any other SoC with DT support upstream. We might also miss chance to get things added to the ACPI spec as we don't care which means that we never be able to use ACPI on similar future platforms even though they get shipped with ACPI. It will be a loop where we constantly keep converting this ACPI shipped platform into DT upstream. IMHO we don't want to be there. -- Regards, Sudeep
