GPIO102 is apparently a navpoint power enable; the old linux-2.6.21-hh20 kernel from handhelds.org defines it thus: #define GPIO_NR_HX4700_SYNAPTICS_POWER_ON 102 I verified that it does need to be asserted before the navpoint will work. I don't possess any hx4700 developer documentation; perhaps Philipp can shed some light on GPIO102. -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
