Summit microelectronics' SMB358 charger chip has
almost the same register map and functionality.
voltage and current table are only differed.
SMB345 charger IC tested in nexus7

+[Required porperties]
+- compatible : "summit,smb345"
+ "summit,smb347"
+- reg : Slave address for i2c interface
+# At least one of following should be set
+ - enable-usb-charging
+ - enable-otg-charging
+ - enable-mains-charging
+
+[Optional properties]
+- interrupt-parent : The phandle for the interrupt controller
+- interrupts : Interrupt line index for mapping
+- en-gpio : Enable charging control
+ : If this is not specified it will use SW (i2c interface)
+
+# Charging constraints
+- max-chg-curr : microamps for charging Maximum current
+- max-chg-volt : microvolts for charging Maximum voltage
+- pre-chg-curr : microamps for Pre-charging current
+- term-curr : microamps for Charging cycle termination current
+- fast-volt-thershold : microvolts for Voltage threshold to transit to fast charge mode
+- mains-curr-limit : micromaps for Maximum input current from AC/DC input
+- usb-curr-limit : microamps for Maximum input current from USB input
+
+# Related thermometer monitoring (Degrees Celsius)
+- chip-temp-threshold : Chip temperature for thermal regulaton. <100, 130>
+- soft-cold-temp-limit : Cold battery temperature for soft alarm. <0, 15>*
+- soft-hot-temp-limit : Hot battery temperature for soft alarm. <40, 55>
+- hard-cold-temp-limit : Cold battery temperature for hard alarm. <0, 15>*
+- hard-hot-temp-limit : Hot battery temperature for hard alarm. <55, 65>
+(* The written temperature has +5'C offset. 0'C -> -5'C, 15'C -> 10'C)
+- soft-comp-method : Soft temperature limit compensation method
+ (Not defined) : Use default setting
+ <0> : Compensation none

Summit microelectronics' SMB358 charger chip has
almost the same register map and functionality.
voltage and current table are only differed.
SMB345 charger IC tested in nexus7

As I wrote last time, I don't think these belong in DT.

These are all properties of the battery, not the charger. See

These too should probably be common. If not they need vendor prefix and
unit suffix. See property-units.txt.

Isn't one example sufficient?
