/** 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.
