/**
* Notes:
*
* This chip has some problems which required careful coding to overcome.
*
* The interrupt pin seems to be unreliable, at least on some boards, so we at most
* use the pin for filtering results to reduce cpu load.
* The symptoms are that readings will just stop due to the irq not being asserted
* even though there are items in the fifo. Another interrupt source such as a
* touch transition will restart the irq.
*
* There is no fifo entry created when a touch up event occurs. We must therefore
* generate a pseudo result on touch up. Fortunately the touch detection appears
* reliable and so we turn off the driver GMOUSE_VFLG_POORUPDOWN setting. In practice
* if touch is up we always return a pseudo event as this saves having to remember the
* previous touch state.
*
* Z readings range from around 90 (fully touched) to around 150 (on the verge of non-touched).
* Note the above is on the STM32F429i-Discovery board. Other boards may be different.
* To be conservative we use 255 as touch off, anything else is a touch on.
*
* GMOUSE_STMPE811_TEST_MODE is designed to be used with the "touch_raw_readings" tool which shows
* a steady stream of raw readings.
*
* Settings that may need tweaking on other hardware:
* The settling times. We have set these conservatively at 1ms.
* The reading window. We set this to 16 just to reduce noise. High-res panels may need a lower value.
