Alexander Shishkin 39f4034693 intel_th: Add driver infrastructure for Intel(R) Trace Hub devices
Intel(R) Trace Hub (TH) is a set of hardware blocks (subdevices) that
produce, switch and output trace data from multiple hardware and
software sources over several types of trace output ports encoded
in System Trace Protocol (MIPI STPv2) and is intended to perform
full system debugging.

For these subdevices, we create a bus, where they can be discovered
and configured by userspace software.

This patch creates this bus infrastructure, three types of devices
(source, output, switch), resource allocation, some callback mechanisms
to facilitate communication between the subdevices' drivers and some
common sysfs attributes.

Intel(R) Trace Hub (TH) is a set of hardware blocks (subdevices) that
produce, switch and output trace data from multiple hardware and
software sources over several types of trace output ports encoded
in System Trace Protocol (MIPI STPv2) and is intended to perform
full system debugging.
This option enables intel_th bus and common code used by TH
subdevices to interact with each other and hardware and for
platform glue layers to drive Intel TH devices.
Say Y here to enable Intel(R) Trace Hub controller support.
