+TPS6507x Power Management Integrated Circuit
+
+Required properties:
+- compatible: "ti,tps6507x"
+- reg: I2C slave address
+- regulators: 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 regulator is matched with the regulator-compatible.
+
+ The valid regulator-compatible values are:
+ tps6507x: vdcdc1, vdcdc2, vdcdc3, vldo1, vldo2
+- xxx-supply: Input voltage supply regulator.
+ These entries are required if regulators are enabled for a device.
+ Missing of these properties can cause the regulator registration
+ fails.
+ If some of input supply is powered through battery or always-on
+ supply then also it is require to have these parameters with proper
+ node handle of always on power supply.
+ tps6507x:
+ vindcdc1_2-supply: VDCDC1 and VDCDC2 input.
+ vindcdc3-supply : VDCDC3 input.
+ vldo1_2-supply : VLDO1 and VLDO2 input.
+
+Regulator Optional properties:
+- defdcdc_default: It's property of DCDC2 and DCDC3 regulators.
+ 0: If defdcdc pin of DCDC2/DCDC3 is pulled to GND.
+ 1: If defdcdc pin of DCDC2/DCDC3 is driven HIGH.
+ If this property is not defined, it defaults to 0 (not enabled).
