+description: |
+ This is a part of device tree bindings for S2M and S5M family of Power
+ Management IC (PMIC).
+
+ The S2MPA01 provides buck and LDO regulators.
+
+ See also Documentation/devicetree/bindings/mfd/samsung,s2mpa01.yaml for
+ additional information and example.

+ May be 0 for disabling the ramp delay on BUCK{1,2,3,4}.
+
+ In the absence of the regulator-ramp-delay property, the default ramp
+ delay will be used.
+
+ Note: Some bucks share the ramp rate setting i.e. same ramp value
+ will be set for a particular group of bucks so provide the same
+ regulator-ramp-delay value for them.
+ Groups sharing ramp rate:
+ * buck{1,6},
+ * buck{2,4},
+ * buck{8,9,10}.
