From a05be99174edc9f258ee68140b71b9645ad977ee Mon Sep 17 00:00:00 2001 From: Ramakrishna Pallala Date: Fri, 30 Nov 2012 13:57:46 +0530 Subject: [PATCH] power_supply: Add watchdog and safety timer expiries under PROP_HEALTH_* As most of the charger chips come with two kinds of safety features related to timing: 1. Watchdog Timer (interms of seconds/mins) 2. Safety Timer (interms of hours) This patch adds these to fault causes in POWER_SUPPLY_PROP_HEALTH_* enums so that whenever there is either watchdog timeout or safety timer timeout driver could notify the user space accurately about the fault and will also be helpful for debug.
