From 3950c7865cd7c963982a2c94457182b96732f4c9 Mon Sep 17 00:00:00 2001 From: Chanwoo Choi Date: Fri, 21 Sep 2012 18:49:37 +0900 Subject: charger-manager: Add support sysfs entry for charger This patch add support sysfs entry for each charger(regulator). Charger-manager use one or more chargers for charging battery but some charger isn't necessary on specific scenario. So, if some charger isn't needed, can disable specific charger through 'externally_control' entry while system is on state and confirm the information(name, state) of charger. The list of added sysfs entry - /sys/class/power_supply/battery/chargers/charger.[index]/name show name of charger(regulator) - /sys/class/power_supply/battery/chargers/charger.[index]/state show either enabled or disabled state of charger - /sys/class/power_supply/battery/chargers/charger.[index]/externally_control If 'externally_control' of specific charger is 1, Charger-manager cannot enable regulator for charging when charger cable is attached and charger must be maintained with disabled state. If 'externally_control' is zero, Charger-manager usually can control to enable/disable regulator.
