regulator-dcdc5, regulator-dcdc6, regulator-ldo1, regulator-ls3.
Each regulator is defined using the standard binding for regulators.

+Optional properties:
+ If any of these properties is absent, the setting will not be touched.
+- strict-supply-voltage: <1|0> Set/Reset STRICT flag in CONFIG1
+- under-voltage-limit: Select 2.75, 2.95, 3.25 or 3.35V as UVLO in CONFIG1
+- under-voltage-hysteresis: Select 200mV or 400mV UVLOHYS in CONFIG2

Example:
tps65218: tps65218@24 {
reg = <0x24>;
compatible = "ti,tps65218";
interrupts = <GIC_SPI 7 IRQ_TYPE_NONE>; /* NMIn */
