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 */
};
};

nxp,enable-modesel-pins:
type: boolean
description:
When enabled, the PMIC will be configured to allow mode selection using
the MODESEL0/1 inputs.
nxp,vin-ilim-microamp:
type: int
default: 425000
enum:
- 85000
- 255000
- 425000
- 595000
- 765000
- 935000
- 1105000

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
- 517 mA/595 mA/684 mA
- 665 mA/765 mA/880 mA
- 813 mA/935 mA/1075 mA
- 961 mA/1105 mA/1271 mA
To disable current limit, set property to zero. Defaults to 425mA, the IC
default value.
nxp,asys-uvlo-sel-millivolt:
type: int
default: 2700
enum:
- 2400
- 2500
- 2600
- 2700
description: |
ASYS UVLO (under voltage lock out) threshold, in millivolts. Defaults to
2700mV to match the IC default value.

enable-inverted:
type: boolean
description: |
If the enable bit should be zero to turn the regulator on, add this
property.
nxp,mode0-microvolt:
type: int
description: |
The voltage level to be configured for mode 0, in microvolts. Setting
this value to zero will disable the source in mode 0.
nxp,mode1-microvolt:
type: int
description: |
The voltage level to be configured for mode 1, in microvolts. Setting
this value to zero will disable the source in mode 1.
nxp,mode2-microvolt:
type: int
description: |
The voltage level to be configured for mode 2, in microvolts. Setting
this value to zero will disable the source in mode 2.
nxp,mode3-microvolt:
type: int
description: |
The voltage level to be configured for mode 3, in microvolts. Setting
this value to zero will disable the source in mode 3.
