1 TI LMU LM363x regulator device tree bindings
2
3 LM363x regulator driver supports LM3631 and LM3632.
4 LM3631 has five regulators and LM3632 supports three regulators.
5
6 Required property:
7 - compatible: "ti,lm363x-regulator"
8
9 Optional properties:
10 LM3632 has external enable pins for two LDOs.
11 - enable-gpios: Two GPIO specifiers for Vpos and Vneg control pins.
12 The first entry is Vpos, the second is Vneg enable pin.

14 Child nodes:
15 LM3631
16 - vboost
17 - vcont
18 - voref
19 - vpos
20 - vneg
21
22 LM3632
23 - vboost
