0001 TPS6507x Power Management Integrated Circuit
0002
0003 Required properties:
0004 - compatible: "ti,tps6507x"
0005 - reg: I2C slave address
0006 - regulators: This is the list of child nodes that specify the regulator
0007 initialization data for defined regulators. Not all regulators for the
0008 given device need to be present. The definition for each of these nodes
0009 is defined using the standard binding for regulators found at
0010 Documentation/devicetree/bindings/regulator/regulator.txt.
0011 The regulator is matched with the regulator-compatible.
0012
0013 The valid regulator-compatible values are:
0014 tps6507x: vdcdc1, vdcdc2, vdcdc3, vldo1, vldo2
0015 - xxx-supply: Input voltage supply regulator.
0016 These entries are required if regulators are enabled for a device.
0017 Missing of these properties can cause the regulator registration
0018 fails.
0019 If some of input supply is powered through battery or always-on
0020 supply then also it is require to have these parameters with proper
0021 node handle of always on power supply.
0022 tps6507x:
0023 vindcdc1_2-supply: VDCDC1 and VDCDC2 input.
0024 vindcdc3-supply : VDCDC3 input.
0025 vldo1_2-supply : VLDO1 and VLDO2 input.
0026
0027 Regulator Optional properties:
0028 - defdcdc_default: It's property of DCDC2 and DCDC3 regulators.
0029 0: If defdcdc pin of DCDC2/DCDC3 is pulled to GND.
0030 1: If defdcdc pin of DCDC2/DCDC3 is driven HIGH.
0031 If this property is not defined, it defaults to 0 (not enabled).
