+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-input-voltage: Minimum CHGIN regulation voltage (in microvolts). Must be
+                     one of: 4000000, 4100000, 4200000, 4300000, 4400000,
+                     4500000, 4600000, 4700000.
+- current-limit:     CHGIN input current limit (in microamps). Must be one of:
+                     95000, 190000, 285000, 380000, 475000.

Unit suffix? Really, these should be common properties. We have
some I think. Charger bindings are a mess though...

Do you mean a suffix like: ua for microamps and uv for microvolts? I'm
not seeing any other such properties.

See bindings/property-units.txt
