   13   This is a part of device tree bindings for S2M and S5M family of Power
   14   Management IC (PMIC).
   15 
   16   The S5M8767 provides buck and LDO regulators.
   17 
   18   See also Documentation/devicetree/bindings/mfd/samsung,s5m8767.yaml for
   19   additional information and example.
