[RFC][PATCH 0/4] Describe coresight on R-Mobile A1

[Marek Vasut]

Implement support for ZT trace bus and ZTR trace clock on R-Mobile A1.
Describe coresight topology on R-Mobile A1. 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 A1 User's Manual:
Hardware , Rev.2.00 Sep. 2013 . I currently do not have access to this
hardware, therefore I am sending this as an RFC patchset.
