-Binding for Samsung S2MPA01 regulator block
-===========================================
-
-This is a part of device tree bindings for S2M family multi-function devices.
-More information can be found in bindings/mfd/sec-core.txt file.
-
-The S2MPA01 device provide buck and LDO regulators.
-
-To register these with regulator framework instantiate under main device node
-a sub-node named "regulators" with more sub-nodes for each regulator using the
-common regulator binding documented in:
- - Documentation/devicetree/bindings/regulator/regulator.txt
-
-
-Names of regulators supported by S2MPA01 device:
-	- LDOn
-		  - valid values for n are 1 to 26
-		  - Example: LDO1, LD02, LDO26
-	- BUCKn
-		  - valid values for n are 1 to 10.
-		  - Example: BUCK1, BUCK2, BUCK9
-Note: The 'n' in LDOn and BUCKn represents the LDO or BUCK number
-as per the datasheet of device.
-
-
-Optional properties of buck regulator nodes under "regulators" sub-node:
- - regulator-ramp-delay: ramp delay in uV/us. May be 6250, 12500
-   (default), 25000, or 50000. 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}.
-
-Example:
-
-	s2mpa01_pmic@66 {
-		compatible = "samsung,s2mpa01-pmic";
-		reg = <0x66>;
-
-		regulators {
-			ldo1_reg: LDO1 {
-				regulator-name = "VDD_ALIVE";
-				regulator-min-microvolt = <1000000>;
-				regulator-max-microvolt = <1000000>;
-			};
-
-			ldo2_reg: LDO2 {
-				regulator-name = "VDDQ_MMC2";
-				regulator-min-microvolt = <2800000>;
-				regulator-max-microvolt = <2800000>;
-				regulator-always-on;
-			};
-
-			buck1_reg: BUCK1 {
-				regulator-name = "vdd_mif";
-				regulator-min-microvolt = <950000>;
-				regulator-max-microvolt = <1350000>;
-				regulator-always-on;
-				regulator-boot-on;
-			};
-
-			buck2_reg: BUCK2 {
-				regulator-name = "vdd_arm";
-				regulator-min-microvolt = <950000>;
-				regulator-max-microvolt = <1350000>;
-				regulator-always-on;
-				regulator-boot-on;
-				regulator-ramp-delay = <50000>;
-			};
-		};
-	};
