From: Mathieu Poirier <mathieu.poirier at linaro.org>

This patchset concentrates on enabling HW assisted tracing on ARM
SoCs.  This first wave centers on the basic tracing functionnality,
enabling components such ETM/PTM, funnel, replicator, TMC, TPIU and
ETB.  Subsequent submissions will enable more intricate IP blocks such
as STM and CTI.

Generated traces are encoded in a PFTv1.1 format and can be interpreted
using the procedure detailed here [1] or ptm2human [2]. STM abides to the
widely available STPv2.

Bindings for the driver have been sent separately to the devicetree list.
