-+ * The touchscreen interface operates as follows:

-+ * Initialize:
-+ * Request access to GPIO103 (DAV)
-+ * tsc2005_ts_irq_handler will trigger when DAV line goes down
-+ *
-+ * 1) Pen is pressed against touchscreeen
-+ * 2) TSC2005 performs AD conversion
-+ * 3) After the conversion is done TSC2005 drives DAV line down
-+ * 4) GPIO IRQ is received and tsc2005_ts_irq_handler is called
-+ * 5) tsc2005_ts_irq_handler queues up an spi transfer to fetch
-+ * the x, y, z1, z2 values
-+ * 6) tsc2005_ts_rx() reports coordinates to input layer and
-+ * sets up tsc2005_ts_timer() to be called after TSC2005_TS_SCAN_TIME
-+ * 7) When the penup_timer expires, there have not been DAV interrupts
-+ * during the last 20ms which means the pen has been lifted.
