+Binding for sgm41542 battery charger
+
+Required properties:
+- compatible: "sgm,sgm41542" for sgm41542 Charger Power Supply
+- monitored-battery: phandle of battery characteristics devicetree node
+- input-voltage-limit-microvolt: integer, input voltage level in uV, used to
+				 decrease voltage level when the over current
+				 of the input power source occurs.
+- input-current-limit-microamp: integer, input current value in uA drained by the
+				charger from the power source.Default: 500000 uA (500mA)
+
+child nodes:
+- vbus5v0_typec:
+  Usage: optional
+  Description: Regulator that is used to control the VBUS voltage direction for
+               either USB host mode or for charging on the OTG port.

+Example:
+
+sgm41542: sgm41542@3b {
