This is a current topic with the ACPI working group. We have the following document:

This hasn't been discussed a lot at the meetings I attended.
The bindings management process is being set up within the UEFI Forum, but I'm not sure if/how the existing DT bindings documented in the kernel tree are going to be covered by it ATM.
Al Stone (CCed) pointed me at the following two documents:
http://www.uefi.org/sites/default/files/resources/web-page-v2.pdf http://www.uefi.org/sites/default/files/resources/nic-request-v2.pdf
(the first one being the actual process in so far as it exists). The process appears to be to mail requests in a specific format to the ASWG chairperson (the address is apparently supposed to be awsg@uefi.org). It looks like all the properties are expected to end up in one or more PDF files like the second one.
My initial thought would be to require that we send any DT properties defined for devices with ACPI identifiers registered there and hope the volume doesn't DoS them.
We absolutely need to start registering the existing bindings in there, but that needs to be rate limited somehow, because the process may not be very efficient to start with.
A more defined format for DT documentation that we can script into the ASWG format (or vice versa) might be helpful here, and we should add notes to the DT documentation if this is how we want to proceed.
That's a good point.
Unfortunately, the timing is pretty bad (Thanksgiving) and the closest ASWG meeting is next Thursday, but that one's likely to be busy for other reasons. I presume, then, that the earliest we can seriously get back to that in the ASWG is mid-December.
