Comment(by lindi):

 When I plug the wall charger to freerunner I see

 {{{
 #0  pcf50633_irq (irq=53, data=0xc79bdc00) at
 /local/lindi/neolinux/drivers/mfd/pcf50633-core.c:446

 }}}

 and after that in pcf50633_irq_worker() pcf_int[] has {0x84, 0x0, 0x0,
 0x0, 0x0} which seems to correspond to

 PCF50633_INT1_USBINS    = 0x04, /* USB inserted */

 However, pcf50633_input_probe() only registers itself for the
 PCF50633_IRQ_ONKEYR and PCF50633_IRQ_ONKEYF events so that it can
 report when power button is pressed:

 Event: time 946686973.644550, type 1 (Key), code 116 (Power), value 1
 Event: time 946686973.645172, -------------- Report Sync ------------
 Event: time 946686973.884483, type 1 (Key), code 116 (Power), value 0
 Event: time 946686973.884558, -------------- Report Sync ------------

 Should that Power2 event be added back? I think I know how to add it
 if it is considered useful.
