* Disable driver GPIO functionality.
* CONFIG_ADXL345_GPIOINT_DISABLE
* Disable driver GPIO interrupt functionlality (ignored if GPIO functionality is
* disabled).
* CONFIG_ADXL345_SWAPXY
* Reverse the meaning of X and Y to handle different LCD orientations.
* CONFIG_ADXL345_TEMP_DISABLE
* Disable driver temperature sensor functionality.
* CONFIG_ADXL345_ACTIVELOW
* The ADXL345 interrupt will be inverted. Instead starting low and
* going high, it will start high and will go low when an interrupt
* is fired. Default: Active high/rising edge.
* CONFIG_ADXL345_REGDEBUG
* Enable very low register-level debug output. Requires CONFIG_DEBUG.
* CONFIG_ADXL345_THRESHX and CONFIG_ADXL345_THRESHY
* ADXL345 touchscreen data comes in a a very high rate. New touch positions
* will only be reported when the X or Y data changes by these thresholds.
* This trades reduces data rate for some loss in dragging accuracy. The
* ADXL345 is configure for 12-bit values so the raw ranges are 0-4095. So
* for example, if your display is 320x240, then THRESHX=13 and THRESHY=17
* would correspond to one pixel. Default: 12
