Acer A500 uses Atmel Maxtouch 1386 touchscreen controller. This controller has WAKE line which could be connected to I2C clock lane, dedicated GPIO or fixed to HIGH level. Controller wakes up from a deep sleep when WAKE line is asserted low. Acer A500 has WAKE line connected to I2C clock and Linux device driver doesn't work property without knowing what wakeup method is used by h/w. Add atmel,wakeup-method property to the touchscreen node. Signed-off-by: Dmitry Osipenko <digetx@gmail.com>
