  1TI LMU LM363x regulator device tree bindings
  2
  3LM363x regulator driver supports LM3631 and LM3632.
  4LM3631 has five regulators and LM3632 supports three regulators.
  5
  6Required property:
  7  - compatible: "ti,lm363x-regulator"
  8
  9Optional 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.
