   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.
