   @patacongo one more patch for this chip...  At this point I have the GPIO and SPI portions of the driver fairly well tested.
   
   The undocumented requirement to read the `STMPE811_GPIO_ED` register was unfortunate.  I suspect internally to the chip this register is attached to a state latch that is used to generate the signal to the interrupt controller and they just failed to document it.
