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.
- ti,lcm-en1-gpio: A GPIO specifier for Vpos control pin.
- ti,lcm-en2-gpio: A GPIO specifier for Vneg control 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].
