Pull char/misc driver updates from Greg KH:
 "Here's the big char/misc driver update for 3.19-rc1

  Lots of little things all over the place in different drivers, and a
  new subsystem, "coresight" has been added.  Full details are in the
  shortlog"

+        help
+          This framework provides a kernel interface for the CoreSight debug
+          and trace drivers to register themselves with. It's intended to build
+          a topological view of the CoreSight components based on a DT
+          specification and configure the right serie of components when a
+          trace source gets enabled.

+        help
+          This enables support for CoreSight link and sink drivers that are
+          responsible for transporting and collecting the trace data
+          respectively.  Link and sinks are dynamically aggregated with a trace

+          This enables support for the Trace Memory Controller driver.  Depending
+          on its configuration the device can act as a link (embedded trace router
+          - ETR) or sink (embedded trace FIFO).  The driver complies with the

+          for bridging the gap between the on-chip coresight components and a trace
+          port collection engine, typically connected to an external host for use
+          case capturing more traces than the on-board coresight memory can handle.

+          This driver provides support for processor ETM3.x and PTM1.x modules,
+          which allows tracing the instructions that a processor is executing
+          This is primarily useful for instruction level tracing.  Depending
+          the ETM version data tracing may also be available.
