+The TPS65218 Integrated Power Management Chips.
+These chips are connected to an I2C bus.
+
+Required properties:
+- compatible : Must be "ti,tps65218";
+- interrupts : This I2C device has an IRQ line connected to the main SoC
+- interrupt-controller : Since the tps65218 supports several interrupts
+  internally, it is considered as an interrupt controller cascaded to the SoC.
+- #interrupt-cells = <2>;
+- interrupt-parent : The parent interrupt controller GIC.
+
+Optional nodes:
+- TPS65218 chip has sub modules. Mainly the DCDCs and regulators.
+
+Example:
