rk817-battery
~~~~~~~~~~

Required properties :
 - compatible: "rk817,battery"
 - ocv_table: ocv voltage and soc relation table
 - design_capacity: real capacity tested by tool
 - design_qmax: nominal capacity * 1.1

Optional properties :
 - sleep_enter_current: current threshold of enter relax mode
 - sleep_exit_current: current threshold of exit relax mode
 - sleep_filter_current: current threshold of valid relax mode
 - power_off_thresd: vsys voltage threshold of power off
 - zero_algorithm_vol: voltage threshold of discharge zero algorithm
 - max_soc_offset: soc threshold of correct dsoc as rsoc
 - monitor_sec: poll seconds for battery delay work
 - virtual_power: test mode for none battery
 - energy_mode: try to use all power of battery

Example:

rk817: pmic@20 {
	compatible = "rockchip,rk817";
