+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].
