Thanks for bringing it up.
I have skimmed the PR threads and the discussion seems to be:
1) OP-TEE internal issues
2) DT standards questions and issues
For the DT call we need to focus on #2 above.
We will definitely need Rob for this discussion so we need to do it when
he can join. (If we don't resolve the question in this email thread
before then.)
Context for all:
SDP here is related to DRM protected playback of media streams.

};
};
However it was modified after that.
Oliver: please reply to this thread (on list please) with the final DTS
you are proposing. fix DT conventions and what are you doing with the
no-map property if anything.
Is the memory above meant to be visible to NS world AND S world? Or is
just for secure world.
Thanks,
Bill

All,
I have no agenda for tomorrow's DT call. Does anyone want to bring up
something?
If I have not heard anything by noon UTC tomorrow (3 hours before the
meeting) I will cancel the call.
Thanks,
Bill

fwupd or similar to stage UpdateCapsule()

All,
We have our normal DTE call today at the new time of 15 UK.
HOWEVER, the UK has come off daylight savings time while the US and
others have not.
This means that in the US it looks like the old time.
11 AM Eastern
10 AM Central
9 AM Mountain
8 AM Pacific
This is a single week issue that occurs once in the fall and in the once
spring.
It _should_ appear correct on you calendar.
We said we would discuss devicetree lifecycle at the source level.
We will use the second half of the slides from last time:
