| H A D | coresight-cti-platform.c | diff cffd054f1708a07330536a9704b70bc5d090cd98 Fri Mar 20 11:52:57 CDT 2020 Mike Leach <mike.leach@linaro.org> coresight: cti: Add device tree support for v8 arch CTI
The v8 architecture defines the relationship between a PE, its optional ETM
and a CTI. Unlike non-architectural CTIs which are implementation defined,
this has a fixed set of connections which can therefore be represented as a
simple tag in the device tree.
This patch defines the tags needed to create an entry for this PE/ETM/CTI
relationship, and provides functionality to implement the connection model
in the CTI driver.
