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 {
|

|

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.
