+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.
