PFUZE100 family of regulators
|
||||
|
||||
Required properties:
|
||||
- compatible: "fsl,pfuze100"
|
||||
- reg: I2C slave address
|
||||
- regulators: This is the list of child nodes that specify the regulator
|
||||
initialization data for defined regulators. Please refer to below doc
|
||||
Documentation/devicetree/bindings/regulator/regulator.txt.
|
||||
|
||||
The valid names for regulators are:
|
||||
sw1ab,sw1c,sw2,sw3a,sw3b,sw4,swbst,vsnvs,vrefddr,vgen1~vgen6
|
||||
|
||||
Each regulator is defined using the standard binding for regulators.
|
||||
|
||||
Example:
|
||||
|
||||
pmic: pfuze100@08 {
|
||||
compatible = "fsl,pfuze100";
|
||||
reg = <0x08>;
