41 * The switch LUT's coding defines a sink for each
42 * single channel ID + channel format type. Conversely
43 * the sink (i.e. an input formatter) can be reached
44 * from multiple channel & format type combinations
45 *
46 * LUT[0,1] channel=0, format type {0,1,...31}
47 * LUT[2,3] channel=1, format type {0,1,...31}
48 * LUT[4,5] channel=2, format type {0,1,...31}
49 * LUT[6,7] channel=3, format type {0,1,...31}
50 *
51 * Each register hold 16 2-bit fields encoding the sink
52 * {0,1,2,3}, "0" means unconnected.
53 *
54 * The single FSYNCH register uses four 3-bit fields of 1-hot
55 * encoded sink information, "0" means unconnected.
56 *
57 * The encoding is redundant. The FSYNCH setting will connect
58 * a channel to a sink. At that point the LUT's belonging to
59 * that channel can be directed to another sink. Thus the data
60 * goes to another place than the synch
