Hi Leo,
There are additional CTI components on the DB410c - I think there is information on base addresses for these - but there is no information on connectivity between the CTIs and any components such as STM / ETR etc for any of the in / out signal lines. Therefore we omitted these from the original DT when adding the other CTI devices.
It could well be that there are signals from the STM to a CTI, and if the information could be found then it would be useful to add - but I have not seen this information anywhere - and it is the sort of thing that is often missed out of hardware manuals. It might be possible to deduce some information using the Coresight intergration management registers - but this would involve a lot of trial and error testing
Okay, let's firstly merge the STM binding patch and later can consider to enable DT binding between CTI and STM if have sufficient info.
Thanks a lot for confirmation.
