+ * 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
