/*
 * The switch LUT's coding defines a sink for each
 * single channel ID + channel format type. Conversely
 * the sink (i.e. an input formatter) can be reached
 * from multiple channel & format type combinations
 *
 * LUT[0,1] channel=0, format type {0,1,...31}
 * LUT[2,3] channel=1, format type {0,1,...31}
 * LUT[4,5] channel=2, format type {0,1,...31}
 * LUT[6,7] channel=3, format type {0,1,...31}
 *
 * Each register hold 16 2-bit fields encoding the sink
 * {0,1,2,3}, "0" means unconnected.
 *
 * The single FSYNCH register uses four 3-bit fields of 1-hot
 * encoded sink information, "0" means unconnected.
 *
 * The encoding is redundant. The FSYNCH setting will connect
 * a channel to a sink. At that point the LUT's belonging to
 * that channel can be directed to another sink. Thus the data
 * goes to another place than the synch
