+
+Required Properties:
+-compatible: "ti,tps65090"
+-reg: I2C slave address

+
+        tps65090@48 {
+                compatible = "ti,tps65090";
+                reg = <0x48>;
+                interrupts = <0 88 0x4>;
+
+                ti,enable-low-current-chrg;
+
+                regulators {
