+/** A note about RMI4 F11 register structure.
+ *
+ * The properties for
+ * a given sensor are described by its query registers.  The number of query
+ * registers and the layout of their contents are described by the F11 device
+ * queries as well as the sensor query information.
+ *
+ * Similarly, each sensor has control registers that govern its behavior.  The
+ * size and layout of the control registers for a given sensor can be determined
+ * by parsing that sensors query registers.
+ *
+ * And in a likewise fashion, each sensor has data registers where it reports
+ * its touch data and other interesting stuff.  The size and layout of a
+ * sensors data registers must be determined by parsing its query registers.
+ *
+ * The short story is that we need to read and parse a lot of query
+ * registers in order to determine the attributes of a sensor. Then
+ * we need to use that data to compute the size of the control and data
+ * registers for sensor.
+ *
+ * The end result is that we have a number of structs that aren't used to
+ * directly generate the input events, but their size, location and contents
+ * are critical to determining where the data we are interested in lives.
+ *
+ * At this time, the driver does not yet comprehend all possible F11
+ * configuration options, but it should be sufficient to cover 99% of RMI4 F11
+ * devices currently in the field.

+ * finger tracking provided by the manual tracking and motion sensitivity
+ * options.
