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 */
|
|
|
|
|
};
|
|
|
|
|
};
