Subject: [PATCH 0/5] power: supply: Add several features support in
 qcom-battmgr driver

Add following features in qcom-battmgr drivers as the battery management
firmware has provided such capabilities:
 - Add resistance power supply property in core driver and qcom-battmgr
   driver to get battery resistance
 - Add state_of_health power supply property in core driver and
   qcom-battmgr driver to get battery health percentage
 - Add charge control start/end threshold control by using
   charge_control_start_threshold and charge_control_end_threshold power
   supply properties

The changes have been tested on QRD8650 device based on qcom/linux.git
for-next commit f8d04825b12f42ec8198dee1ab4654792f9ac231.
