Probably needs "max," prefix. And .. what does this mean? Will charger
shutdown if input is less than this?

"current-limit-microamp", I guess. And probably "max,current-limit-microamp".

The charger will enter the undervoltage lockout state and stop
charging, this is explained in the manual, so I don't think the
bindings are the right place to add this information.

+Battery charger driver for MAX77650 PMIC from Maxim Integrated.
+
+This module is part of the MAX77650 MFD device. For more details
+see Documentation/devicetree/bindings/mfd/max77650.txt.
+
+The charger is represented as a sub-node of the PMIC node on the device tree.
+
+Required properties:
+--------------------
+- compatible:		Must be "maxim,max77650-charger"
+
+Optional properties:
+--------------------
+- min-microvolt:	Minimum CHGIN regulation voltage (in microvolts). Must be
+			one of: 4000000, 4100000, 4200000, 4300000, 4400000,
+			4500000, 4600000, 4700000.
+- curr-lim-microamp:	CHGIN input current limit (in microamps). Must be one of:
+			95000, 190000, 285000, 380000, 475000.
+
+Example:
+--------
+
+	charger {
+		compatible = "maxim,max77650-charger";
+		min-microvolt = <4200000>;
+		curr-lim-microamp = <285000>;
+	};
