[PATCH 4/5] coresight-stm: adding driver for CoreSight STM component

From: Pratik Patel <redacted>

This driver adds support for the STM CoreSight IP block,
allowing any system compoment (HW or SW) to log and
aggregate messages via a single entity.

The STM exposes an application defined number of channels
called stimulus port.  Configuration is done using entries
in sysfs and channels made available to userspace via devfs.

I somehow missed it when it was posted, but anyway. It looks like we are
solving a very similar problem (the STM device) and I'd like to propose
a generic and architecture independent solution [1]. I also took the
liberty to copy you and Pratik on those patches.
