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: | |
| 34 | ||
| 35 | pmu: tps6507x@48 { | |
| 36 | compatible = "ti,tps6507x"; | |
