* The touchscreen interface operates as follows:
*
* 1) Pen is pressed against the touchscreen.
* 2) TSC2005 performs AD conversion.
* 3) After the conversion is done TSC2005 drives DAV line down.
* 4) GPIO IRQ is received and tsc2005_irq_thread() is scheduled.
* 5) tsc2005_irq_thread() queues up an spi transfer to fetch the x, y, z1, z2
* values.
* 6) tsc2005_irq_thread() reports coordinates to input layer and sets up
* tsc2005_penup_timer() to be called after TSC2005_PENUP_TIME_MS (40ms).
* 7) When the penup timer expires, there have not been touch or DAV interrupts
* during the last 40ms which means the pen has been lifted.
*
* ESD recovery via a hardware reset is done if the TSC2005 doesn't respond
* after a configurable period (in ms) of activity. If esd_timeout is 0, the
* watchdog is disabled.
