-+ *    Request access to GPIO103 (DAV)
-+ *    tsc2301_ts_irq_handler will trigger when DAV line goes down
-+ *
-+ *  1) Pen is pressed against touchscreeen
-+ *  2) TSC2301 performs AD conversion
-+ *  3) After the conversion is done TSC2301 drives DAV line down
-+ *  4) GPIO IRQ is received and tsc2301_ts_irq_handler is called
-+ *  5) tsc2301_ts_irq_handler queues up an spi transfer to fetch
-+ *     the x, y, z1, z2 values
-+ *  6) SPI framework calls tsc2301_ts_rx after the coordinates are read
-+ *  7) When the penup_timer expires, there have not been DAV interrupts
-+ *     during the last 20ms which means the pen has been lifted.

-+ * Some notes about TSC2301:
-+ * - PLL will stop when DAC and ADC's are powered down.
-+ * - Touchscreen will stop working when audio part is powered up and if audio
-+ *   MCLK is stopped. Problem is avoided if audio is powered down before
-+ *   stopping MCLK.
-+ * - Audio DAC or audio outputs will activate only after 100 msec from the
-+ *   chip power-up. Reason seems to be VCM since there is no this delay if the
-+ *   chip and VCM (bit AVPD on PD/MISC) were not powered down. The chip will
-+ *   consume about 1 mA if all other audio blocks are powered down except the
-+ *   chip itself and VCM. Full power down consumes only about few uA.
-+ * - Power-down transition could happen earliest about 100 msec after the chip
-+ *   power-up. Otherwise power-down will fail if there is no that 100 msec
-+ *   on time before it. It's not obvious why is that since chip reports
-+ *   power-up to be completed and also PLL output on GPIO_0 is active in few
-+ *   milliseconds.
