power_supply: Add min/max alert properties for CAPACITY, TEMP, TEMP_AMBIENT
Minimum and maximum alerts on power supply properties will help or allow the user space to "proactively" create policies like connect/disconnect charger or stop/start the user apps based on capacity or temperature parameters. These parameters can be used to avoid unnecessary polling from user space and even from kernel space if the underlying HW can support INT triggers (ex: max17042/47). This patch adds the following power supply alert type properties: CAPACITY_ALERT_MIN CAPACITY_ALERT_MAX TEMP_ALERT_MIN TEMP_ALERT_MAX TEMP_AMBIENT_ALERT_MIN TEMP_AMBIENT_ALERT_MAX Signed-off-by: Ramakrishna Pallala <ramakrishna.pallala@intel.com> Signed-off-by: Anton Vorontsov <anton.vorontsov@linaro.org>
