+smb347_charger bindings
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+[Required porperties]
+- compatible : "summit,smb347"
+- reg : Slave address for i2c interface
+# At least one of followings 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
+- enable-chg-ctrl : Enable charging control
+ <0> : SW (i2c interface)
+ <1> : Pin control (Active Low)
+ <2> : Pin control (Active High)
+# Charging constraints
+- max-chg-curr : Maximum current for charging (in uA)
+- max-chg-volt : Maximum voltage for charging (in uV)
+- pre-chg-curr : Pre-charging current (in uA)
+- term-curr : Charging cycle termination current (in uA)
+- fast-volt-thershold : Voltage threshold to transit to fast charge mode (in uV)
+- mains-curr-limit : Maximum input current from AC/DC input (in uA)
+- usb-curr-limit : Maximum input current from USB input (in uA)
+
+# Related thermometer monitoring (in degree C)
+- 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
+ <1> : Charge current compensation
+ <2> : Voltage compensation
+
+Example:
+ smb347@7f {
+ compatible = "summit,smb347";
+ reg = <0x7f>;
+ status = "okay";
+
+ max-chg-curr = <1800000>;
+ mains-curr-limit = <2000000>;
+ usb-curr-limit = <450000>;
+
+ chip-temp-thershold = <110>;
+
+ enable-usb-charging;
+ enable-mains-charging;
+
+ enable-chg-ctrl = <2>; /* Pin control (Active High) */
+ };
