|
||
* 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.
