[PATCH v2] coresight-stm: adding driver for CoreSight STM component

2015-02-25 Thread Mathieu Poirier
From: Pratik Patel 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 an
