From ed2249841109beea80ec5cfdd2633e6025258989 Mon Sep 17 00:00:00 2001 From: Liam Breck Date: Wed, 18 Jan 2017 09:26:48 -0800 Subject: [PATCH] power: supply: bq24190_charger: Fix irq trigger to IRQF_TRIGGER_FALLING commit 767eee362fd72bb2ca44cc80419ca4b38c6d8369 upstream. The interrupt signal is TRIGGER_FALLING. This is is specified in the data sheet PIN FUNCTIONS: "The INT pin sends active low, 256us pulse to host to report charger device status and fault." Also the direction can be seen in the data sheet Figure 37 "BQ24190 with D+/D- Detection and USB On-The-Go (OTG)" which shows a 10k pull-up resistor installed for the sample configurations.
