Subject: [PATCH] regulator: da9210: add Device Tree binding documentation

DA9210 Device Tree support currently only handles standard regulator DT
bindings. This patch adds compulsory minimal documentation to describe
this.

Hi Mark,
Is a separate patch like this one ok or you'd prefer me to re-post the 
original series and merge this with the DT implementation?

+* 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";
+		reg = <0x68>;
+
+		regulator-min-microvolt = <900000>;
+		regulator-max-microvolt = <1000000>;
