Intel(R) Management Engine (ME) Client bus API
-===============================================
+==============================================
Rationale
=========
+
MEI misc character device is useful for dedicated applications to send and receive
data to the many FW appliance found in Intel's ME from the user space.
However for some of the ME functionalities it make sense to leverage existing software
MEI CL bus API
-===========
+==============
+
A driver implementation for an MEI Client is very similar to existing bus
based device drivers. The driver registers itself as an MEI CL bus driver through
the mei_cl_driver structure:
Example

As a theoretical example let's pretend the ME comes with a "contact" NFC IP.
The driver init and exit routines for this device would look like:

Introduction
-=======================
+============
The Intel Management Engine (Intel ME) is an isolated and protected computing
resource (Co-processor) residing inside certain Intel chipsets. The Intel ME

+Intel AMT OS Health Watchdog
+============================
+
The Intel AMT Watchdog is an OS Health (Hang/Crash) watchdog.
Whenever the OS hangs or crashes, Intel AMT will send an event
to any subscriber to this event. This mechanism means that
If the Intel AMT Watchdog feature does not exist (i.e. the connection failed),
the Intel MEI driver will disable the sending of heartbeats.
