1	TPS6507x Power Management Integrated Circuit
2	
3	Required properties:
4	- compatible: "ti,tps6507x"
5	- reg: I2C slave address
6	- regulators: This is the list of child nodes that specify the regulator
7	  initialization data for defined regulators. Not all regulators for the
8	  given device need to be present. The definition for each of these nodes
9	  is defined using the standard binding for regulators found at
10	  Documentation/devicetree/bindings/regulator/regulator.txt.
11	  The regulator is matched with the regulator-compatible.
12	
13	  The valid regulator-compatible values are:
14	  tps6507x: vdcdc1, vdcdc2, vdcdc3, vldo1, vldo2
15	- xxx-supply: Input voltage supply regulator.
16	  These entries are required if regulators are enabled for a device.
17	  Missing of these properties can cause the regulator registration
18	  fails.
19	  If some of input supply is powered through battery or always-on
20	  supply then also it is require to have these parameters with proper
21	  node handle of always on power supply.
22	  tps6507x:
23	       vindcdc1_2-supply: VDCDC1 and VDCDC2 input.
24	       vindcdc3-supply  : VDCDC3 input.
25	       vldo1_2-supply   : VLDO1 and VLDO2 input.
26	
27	Regulator Optional properties:
28	- defdcdc_default: It's property of DCDC2 and DCDC3 regulators.
29				0: If defdcdc pin of DCDC2/DCDC3 is pulled to GND.
30				1: If defdcdc pin of DCDC2/DCDC3 is driven HIGH.
31	  If this property is not defined, it defaults to 0 (not enabled).
32	
33	Example:
