1TPS6507x Power Management Integrated Circuit
2
3Required 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
27Regulator 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).
