| Nordic nPM1300 PMIC |
| |
| The PMIC has two buck converters and two LDOs. |
| The regulators need to be defined as child nodes, strictly following the |
| BUCK1,2 LDO1..2, node names. For |
| example: |
| |
| pmic@6b { |
| reg = <0x6b>; |
| ... |
| regulators { |
| compatible = "nordic,npm1300-regulator"; |
| |
| BUCK1 { |
| /* all properties for BUCK1 */ |
| }; |
| BUCK2 { |
| /* all properties for BUCK2 */ |
| }; |
| LDO1 { |
| /* all properties for LDO1 */ |
| }; |
| LDO2 { |
| /* all properties for LDO2 */ |
| }; |
| }; |
| }; |
| |
| compatible: "nordic,npm1300-regulator" |

| Set_dvs_mode will drive these pins as follows: |
| DVS mode 1 will enable the first pin |
| DVS mode 2 will enable the second pin |
| DVS mode 3 will drive the first and second pins |
| etc. |
| The effect of the mode change is defined by the enable-gpios |
| and pwm_gpios fields for each of the regulator blocks. |
