+ * The "master" is actually the second controller to be detected. The
+ * logic on the board uses logical numbers for the 4 controlers, but

+ * with the analog switch, we need to "map" from the detection sequence
+ * over to the board's logical controller number. This mapping sequence
+ * is {3, 0, 2, 1}, i.e. the first controller to be detected is logical
+ * unit 3, the second (which is the master) is logical unit 0, etc.
+ * We need to maintain the status of the analog switch (which of the 16

+ * A data value (gpio bit 7) of '1' enables the switch, and '0' disables
+ * the switch. A STROBE bit (gpio bit 8) latches the data value into the
