This patch adds basic Device Tree support to the da9210 regulator driver -
with no special properties, since also driver's platform data only contains
standard regulator initialisation parameters.

+* Dialog Semiconductor DA9210 Voltage Regulator

+Required properties:
+
+- compatible: must be "diasemi,da9210"
+- reg: the i2c slave address of the regulator. It should be 0x68.
+
+Any standard regulator properties can be used to configure the single da9210
+DCDC.
+
+Example:
+
+ da9210@68 {
+ compatible = "diasemi,da9210";
