-/*
- * LIMITATIONS:
- *	The SSI unit has only one physical data line, so full duplex is
- *	impossible.  This can be remedied  on the  SH7760 by  using the
- *	other SSI unit for recording; however the SH7780 has only 1 SSI
- *	unit, and its pins are shared with the AC97 unit,  among others.
- *
- * FEATURES:
- *	The SSI features "compressed mode": in this mode it continuously
- *	streams PCM data over the I2S lines and uses LRCK as a handshake
- *	signal.  Can be used to send compressed data (AC3/DTS) to a DSP.
- *	The number of bits sent over the wire in a frame can be adjusted
- *	and can be independent from the actual sample bit depth. This is
- *	useful to support TDM mode codecs like the AD1939 which have a
- *	fixed TDM slot size, regardless of sample resolution.
