TI LMU LM363x regulator device tree bindings
|
|
|
|
LM363x regulator driver supports LM3631 and LM3632.
|
|
LM3631 has five regulators and LM3632 supports three regulators.
|
|
|
|
Required property:
|
|
- compatible: "ti,lm363x-regulator"
|
|
|
|
Optional properties:
|
|
LM3632 has external enable pins for two LDOs.
|
|
- enable-gpios: Two GPIO specifiers for Vpos and Vneg control pins.
|
|
The first entry is Vpos, the second is Vneg enable pin.
|
|
|
|
Child nodes:
|
|
LM3631
|
|
- vboost
|
|
- vcont
|
|
- voref
|
|
- vpos
|
|
- vneg
|
|
|
|
LM3632
|
|
- vboost
|
|
- vpos
|
|
- vneg
|
|
|
|
Optional properties of a child node:
|
|
Each sub-node should contain the constraints and initialization.
|
|
Please refer to [1].
|
|
|
|
Examples: Please refer to ti-lmu dt-bindings [2].
