Memory mapped accesses to ETM registers on Krait pass3 cause
intermittent hangs that lock up all the Kraits and their T32
sessions.
This is currently under debug but until this is resolved
error out of ETM probe for Krait pass3.

Bottom 8 bits [7:0] of ETMSYNCFR are reserved on Krait pass3. This
means only bits [11:8] are valid since bits [31:12] are specified
as reserved by PFTv1.1 specification.
Use an appropriate value for the synchronization frequency in light
of this change on Krait pass3.

Have STM hardware event and port enable sysfs nodes to allow users to
selectively enable and disable either hardware events or stimulus
ports while STM as a whole is enabled.

Provide CoreSight abort debug api to stop the active trace sink
from any context. This is a best effort api that can be used to
abruptly stop and disable the current trace sink from anywhere
in the kernel to avoid tracing and hence polluting the trace data
after the point of interest has been executed.

This driver manages CoreSight TMC (Trace Memory Controller) which
can be pre-configured as an ETF (Embedded Trace FIFO) or ETR
(Embedded Trace Router). ETF when configured in circular buffer mode
acts as an ETB (Embedded Trace Buffer).

Using devm_* apis helps in simplifying driver init and exit paths,
hence switch to using them in the driver probe calls.

This driver manages the CoreSight Replicator that has been made
programmable to allow software to turn of the replicator branch
to sink that is not being used. This avoids trace traffic to the
unused/non-current sink from causing backpressure that results in
overflows at the source.

Some targets require tpiu is disabled before other sinks like ETB
get enabled to get proper ETM trace.

This allows users to switch between available trace sinks thus
providing user to choose the best switch for the debug use case.
