    1 TPS65218 family of regulators
    2 
    3 Required properties:
    4 - compatible: "ti,tps65218"
    5 - reg: I2C slave address
    6 
    7 - List of regulators provided by this controller, must be named
    8   after their hardware counterparts: dcdc[1-6] and ldo1
    9 - This is the list of child nodes that specify the regulator
   10   initialization data for defined regulators. Not all regulators for the given
   11   device need to be present. The definition for each of these nodes is defined
   12   using the standard binding for regulators found at ./regulator.txt.
   13 
   14   The valid names for regulators are:
   15   tps65217: regulator-dcdc1, regulator-dcdc2, regulator-dcdc3, regulator-dcdc4,
   16   regulator-dcdc5, regulator-dcdc6, regulator-ldo1, regulator-ls3.
   17   Each regulator is defined using the standard binding for regulators.
   18 
   19 Example:
   20 tps65218: tps65218@24 {
   21         reg = <0x24>;
   22         compatible = "ti,tps65218";
   23         interrupts = <GIC_SPI 7 IRQ_TYPE_NONE>; /* NMIn */
   24         interrupt-controller;
   25         #interrupt-cells = <2>;
