+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.
