- qcom,fg-sys-min-voltage

	Usage:      optional

	Value type: <u32>

	Definition: The voltage threshold (in mV) which describes the system

		    minimum voltage as per the hardware recommendation. This

		    is not used for any configuration but only for calculating

		    the available power. If this property is not specified,

		    then the default value used is 2800 mV.
