This updates the device tree according to the preferred way of parsing
the nodes using the regulator framework.

It wasn't exactly clear that the compatible string "added" here is 
already used, so it looked like you were breaking compatibility at 
first. Otherwise,

 TPS65218 family of regulators
 
 Required properties:
-For tps65218 regulators/LDOs
-- compatible:
-  - "ti,tps65218-dcdc1" for DCDC1
-  - "ti,tps65218-dcdc2" for DCDC2
-  - "ti,tps65218-dcdc3" for DCDC3

-Optional properties:
-- Any optional property defined in bindings/regulator/regulator.txt
+- compatible: "ti,tps65218"
+- reg: I2C slave address
+- list of regulators provided by this controller, must be named
+  after their hardware counterparts: dcdc[1-6] and ldo1
+- This is the list of child nodes that specify the regulator
+  initialization data for defined regulators. Not all regulators for the given
+  device need to be present. The definition for each of these nodes is defined
+  using the standard binding for regulators found at
+  Documentation/devicetree/bindings/regulator/regulator.txt.
+
+  The valid names for regulators are:
+  tps65217: regulator-dcdc1, regulator-dcdc2, regulator-dcdc3, regulator-dcdc4,
+  regulator-dcdc5, regulator-dcdc6, regulator-ldo1, regulator-ls3
+  Each regulator is defined using the standard binding for regulators.
