I try to create bare metal application for TI am335x soc based board. One thing I need to do is to invoke callback1 on rising edge and callback2 on falling edge. From the datasheet I figured out, that simultaneous detection for rising and falling edge could be enabled by writing 1 << pin to RISINGDETECT and FALLINGDETECT GPIO registers.
