description: |
  This is part of the device tree bindings for the S2MG11 Power Management IC
  (PMIC).
 
  The S2MPG11 PMIC provides 12 buck, 1 buck-boost, and 15 LDO regulators.
 
  See also Documentation/devicetree/bindings/mfd/samsung,s2mps11.yaml for
  additional information and example.

          These rails can be controlled via one of several possible external
          (hardware) signals. If so, this property configures the signal the PMIC
          should monitor. The following values generally corresponding to the
          respective on-chip pin are valid:
            - 0 # S2MPG11_EXTCTRL_PWREN - PWREN pin
            - 1 # S2MPG11_EXTCTRL_PWREN_MIF - PWREN_MIF pin
