Pull regulator updates from Mark Brown:
 "This has been a very quiet release for the regulator API: there's one
  new driver for the Maxim MAX20411, some DT schema conversions and some
  small tweaks and improvements but really nothing major at all"

-ACT88xx regulators
--------------------
-
-Required properties:
-- compatible: "active-semi,act8846" or "active-semi,act8865" or "active-semi,act8600"
-- reg: I2C slave address
-
-Optional properties:
-- system-power-controller: Telling whether or not this pmic is controlling
-  the system power. See Documentation/devicetree/bindings/power/power-controller.txt .
-- active-semi,vsel-high: Indicates the VSEL pin is high.
-  If this property is missing, assume the VSEL pin is low(0).
-
-Optional input supply properties:
-- for act8600:
-  - vp1-supply: The input supply for DCDC_REG1
-  - vp2-supply: The input supply for DCDC_REG2
-  - vp3-supply: The input supply for DCDC_REG3
-  - inl-supply: The input supply for LDO_REG5, LDO_REG6, LDO_REG7 and LDO_REG8
-  SUDCDC_REG4, LDO_REG9 and LDO_REG10 do not have separate supplies.
-- for act8846:
-  - vp1-supply: The input supply for REG1

-  - inl45-supply: The input supply for LDO_REG1 and LDO_REG2
-  - inl67-supply: The input supply for LDO_REG3 and LDO_REG4
-
-Any standard regulator properties can be used to configure the single regulator.
-regulator-initial-mode, regulator-allowed-modes and regulator-mode could be specified
-for act8865 using mode values from dt-bindings/regulator/active-semi,8865-regulator.h
-file.
-
-The valid names for regulators are:
-	- for act8846:
-	REG1, REG2, REG3, REG4, REG5, REG6, REG7, REG8, REG9, REG10, REG11, REG12
-	- for act8865:

-Binding for Fairchild FAN53555 regulators
-
-Required properties:
-  - compatible: one of "fcs,fan53555", "fcs,fan53526", "silergy,syr827",
-		"silergy,syr828" or "tcs,tcs4525".
-  - reg: I2C address
-
-Optional properties:
-  - fcs,suspend-voltage-selector: declare which of the two available
-		voltage selector registers should be used for the suspend
-		voltage. The other one is used for the runtime voltage setting
-		Possible values are either <0> or <1>
-  - vin-supply: regulator supplying the vin pin
-
-Example:
-
-	regulator@40 {
-		compatible = "fcs,fan53555";
-		regulator-name = "fan53555";
-		regulator-min-microvolt = <1000000>;
-		regulator-max-microvolt = <1800000>;
-		vin-supply = <&parent_reg>;
-		fcs,suspend-voltage-selector = <1>;
