From bb879101606dd7235d8f4ecd0f707b63281d0838 Mon Sep 17 00:00:00 2001 From: Rhyland Klein Date: Mon, 28 Feb 2011 16:55:28 -0800 Subject: bq20z75: Add optional battery detect gpio Adding support for an optional gpio for battery detection. This is passed in through the i2c platform data. It also accepts another field, battery_detect_present to signify the gpio state which means the battery is present, either 0 (low) or 1 (high).
