in /drivers/mfd/tps65217.c i believe this is where the magic happens, and

if (int_reg & TPS65217_INT_PBI) {
/* Handle push button */
dev_dbg(tps->dev, "power button status change\n");
input_report_key(tps->pwr_
but, KEY_POWER,
status_reg & TPS65217_STATUS_PB);
input_sync(tps->pwr_but);
}
if (int_reg & TPS65217_INT_ACI) {
/* Handle AC power status change */
