+Description:
+                High Speed Synchronous Serial Interface (HSI) is a
+                serial interface mainly used for connecting application
+                engines (APE) with cellular modem engines (CMT) in cellular
+                handsets.
+                The bus will be populated with devices (hsi_clients) representing
+                the protocols available in the system. Bus drivers implement
+                those protocols.
