| NXP PCA9420 PMIC |
| |
| The PMIC has two buck converters and two LDOs. All need to be defined as |
| children nodes, strictly following the BUCK1, BUCK2, LDO1 and LDO2 node names. |
| For example: |
| |
| pmic@61 { |
| reg = <0x61>; |
| ... |
| BUCK1 { |
| /* all properties for BUCK1 */ |
| }; |
| BUCK2 { |
| /* all properties for BUCK2 */ |
| }; |
| LDO1 { |
| /* all properties for LDO1 */ |
| }; |
| LDO2 { |
| /* all properties for LDO2 */ |
| }; |
| }; |

| description: |
| When enabled, the PMIC will be configured to allow mode selection using |
| the MODESEL0/1 inputs. |

| VIN input current limit, in microamperes. Value reflects typical value, |
| below you can find min/typical/max values: |
| |
| - 74 mA/85 mA/98 mA |
| - 222 mA/255 mA/293 mA |
| - 370 mA/425 mA/489 mA |

| To disable current limit, set property to zero. Defaults to 425mA, the IC |
| default value. |
