Monolithic Power Systems MP8867/MP8869 voltage regulator
|
||||
|
||||
Required properties:
|
||||
- compatible: Must be one of the following.
|
||||
"mps,mp8867"
|
||||
"mps,mp8869"
|
||||
- reg: I2C slave address.
|
||||
- enable-gpios: enable gpios.
|
||||
- mps,fb-voltage-divider: An array of two integers containing the resistor
|
||||
values R1 and R2 of the feedback voltage divider in kilo ohms.
|
||||
|
||||
Any property defined as part of the core regulator binding, defined in
|
||||
./regulator.txt, can also be used.
|
||||
|

Example:
|
||||
|
||||
vcpu: regulator@62 {
