From 4b082ac6b7687d564065cdb65393b8d1ed5e1a03 Mon Sep 17 00:00:00 2001 From: "lecopzer@gmail.com" Date: Fri, 13 Sep 2019 02:25:59 +0800 Subject: [PATCH] test_power: Add CHARGE_COUNTER properties CHARGE_COUNTER is really general in other power supply drivers and Android also has an interface to monitor CHARGE_COUNTER, so let's add it into test framework. Set default as -1000 is because the default status is POWER_SUPPLY_STATUS_DISCHARGING, which means the counter should be negative, and 1000 means not zero but small enough.
