Subject: [RFC PATCH 0/5] Adding graph handling to device connection API

Hi,

I'm only presenting my idea with these how I think we should be able
to deal with graphs in the API, so these are completely untested, and
obviously I can't say for certain if the idea works or not.

I will try to test these using custom ACPI tables, but of course these
should be tested on DT platform as well, so if somebody can do that, I
would much appreciate.

Thanks,
