[PATCH 0/4] Describe coresight on R-Mobile APE6

Implement support for ZT trace bus and ZTR trace clock on R-Mobile APE6.
Describe coresight topology on R-Mobile APE6. Extend the current PTM node
with connection funnel, TPIU, ETB and replicator. The coresight on this
hardware is clocked from the ZT/ZTR trace clock.

Please note that this is written according to R-Mobile APE6 User's Manual
Rev. 0.7, Revision Date: 22-Jan-2013. I currently do not have access to
this hardware.
