Anatop Voltage regulators
|
|
|
|
Required properties:
|
|
- compatible: Must be "fsl,anatop-regulator"
|
|
- anatop-reg-offset: Anatop MFD register offset
|
|
- anatop-vol-bit-shift: Bit shift for the register
|
|
- anatop-vol-bit-width: Number of bits used in the register
|
|
- anatop-min-bit-val: Minimum value of this register
|
|
- anatop-min-voltage: Minimum voltage of this regulator
|
|
- anatop-max-voltage: Maximum voltage of this regulator
|
|
|
|
Optional properties:
|
|
- anatop-delay-reg-offset: Anatop MFD step time register offset
|
|
- anatop-delay-bit-shift: Bit shift for the step time register
|
|
- anatop-delay-bit-width: Number of bits used in the step time register
|
|
- vin-supply: The supply for this regulator
|
|
|
|
Any property defined as part of the core regulator
|
|
binding, defined in regulator.txt, can also be used.

Example:
|
|
|
|
regulator-vddpu {
|
|
compatible = "fsl,anatop-regulator";
|

|
regulator-max-microvolt = <1300000>;
|
|
regulator-always-on;
