		*
		* @use_main, @use_usb, and @use_usb_otg are means to enable/disable

		* example OTG charging controlled via OTG transceiver driver and not by
		* the SMB347 hardware.
		*
		* Hard and soft temperature limit values are given as described in the
		* device data sheet and assuming NTC beta value is %3750. Even if this is
		* not the case, these values should be used. They can be mapped to the
		* corresponding NTC beta values with the help of table %2 in the data
		* sheet. So for example if NTC beta is %3375 and we want to program hard
		* hot limit to be %53 deg C, @hard_hot_temp_limit should be set to %50.
		*
		* If zero value is given in any of the current and voltage values, the
		* factory programmed default will be used. For soft/hard temperature
		* values, pass in %SMB347_TEMP_USE_DEFAULT instead.
