   8 commit 767eee362fd72bb2ca44cc80419ca4b38c6d8369 upstream.
   9
  10 The interrupt signal is TRIGGER_FALLING. This is is specified in the
  11 data sheet PIN FUNCTIONS: "The INT pin sends active low, 256us
  12 pulse to host to report charger device status and fault."
  13
  14 Also the direction can be seen in the data sheet Figure 37 "BQ24190
  15 with D+/D- Detection and USB On-The-Go (OTG)" which shows a 10k
  16 pull-up resistor installed for the sample configurations.
