+* Maxim MAX8997 Voltage and Current Regulator
+
+The Maxim MAX8997 is a multi-function device which includes volatage and
+current regulators, rtc, charger controller and other sub-blocks. It is
+interfaced to the host controller using a i2c interface. Each sub-block is
+addressed by the host system using different i2c slave address. This document
+describes the bindings for 'pmic' sub-block of max8997.
+
+Required properties:
+- compatible: Should be "maxim,max8997-pmic".
+- reg: Specifies the i2c slave address of the pmic block. It should be 0x66.
+
+- max8997,pmic-buck1-dvs-voltage: A set of 8 voltage values in micro-volt (uV)
+ units for buck1 when changing voltage using gpio dvs. Refer to [1] below
+ for additional information.
+
+- max8997,pmic-buck2-dvs-voltage: A set of 8 voltage values in micro-volt (uV)
+ units for buck2 when changing voltage using gpio dvs. Refer to [1] below
+ for additional information.
+
+- max8997,pmic-buck5-dvs-voltage: A set of 8 voltage values in micro-volt (uV)
+ units for buck5 when changing voltage using gpio dvs. Refer to [1] below
+ for additional information.
+
+[1] If none of the 'max8997,pmic-buck[1/2/5]-uses-gpio-dvs' optional
+ property is specified, the 'max8997,pmic-buck[1/2/5]-dvs-voltage'
+ property should specify atleast one voltage level (which would be a
+ safe operating voltage).
+
+ If either of the 'max8997,pmic-buck[1/2/5]-uses-gpio-dvs' optional
+ property is specified, then all the eigth voltage values for the
+ 'max8997,pmic-buck[1/2/5]-dvs-voltage' should be specified.
+
+Optional properties:
+- interrupt-parent: Specifies the phandle of the interrupt controller to which
+ the interrupts from max8997 are delivered to.
+- interrupts: Interrupt specifiers for two interrupt sources.
+ - First interrupt specifier is for 'irq1' interrupt.
+ - Second interrupt specifier is for 'alert' interrupt.
+- max8997,pmic-buck1-uses-gpio-dvs: 'buck1' can be controlled by gpio dvs.
+- max8997,pmic-buck2-uses-gpio-dvs: 'buck2' can be controlled by gpio dvs.
+- max8997,pmic-buck5-uses-gpio-dvs: 'buck5' can be controlled by gpio dvs.
+
+Additional properties required if either of the optional properties are used:
+- max8997,pmic-ignore-gpiodvs-side-effect: When GPIO-DVS mode is used for
+ multiple bucks, changing the voltage value of one of the bucks may affect
+ that of another buck, which is the side effect of the change (set_voltage).
+ Use this property to ignore such side effects and change the voltage.
+
+- max8997,pmic-buck125-default-dvs-idx: Default voltage setting selected from
+ the possible 8 options selectable by the dvs gpios. The value of this
+ property should be between 0 and 7. If not specified or if out of range, the
+ default value of this property is set to 0.
+
+- max8997,pmic-buck125-dvs-gpios: GPIO specifiers for three host gpio's used
+ for dvs. The format of the gpio specifier depends in the gpio controller.
+
+Regulators: The regulators of max8997 that have to be instantiated should be
+included in a sub-node named 'regulators'. Regulator nodes included in this
+sub-node should be of the format as listed below.
+
+ regulator_name {
+ standard regulator bindings here
+ };
+
+The following are the names of the regulators that the max8997 pmic block
+supports. Note: The 'n' in LDOn and BUCKn represents the LDO or BUCK number
+as per the datasheet of max8997.
+
+ - LDOn
+ - valid values for n are 1 to 18 and 21
+ - Example: LDO0, LD01, LDO2, LDO21
+ - BUCKn
+ - valid values for n are 1 to 7.
+ - Example: BUCK1, BUCK2, BUCK3, BUCK7
+
+ - ENVICHG: Battery Charging Current Monitor Output. This is a fixed
+ voltage type regulator
+
+ - ESAFEOUT1: (ldo19)
+ - ESAFEOUT2: (ld020)
+
+ - CHARGER_CV: main battery charger voltage control
+ - CHARGER: main battery charger current control
+ - CHARGER_TOPOFF: end of charge current threshold level
+
+The bindings inside the regulator nodes use the standard regulator bindings
+which are documented elsewhere.
+
+Example:
+
+ max8997_pmic@66 {

+Versatile Express voltage regulators
+------------------------------------
+
+Requires node properties:
+- "compatible" value: "arm,vexpress-volt"
+- "arm,vexpress-sysreg,func" when controlled via vexpress-sysreg
+ (see Documentation/devicetree/bindings/arm/vexpress-sysreg.txt
+ for more details)
+
+Required regulator properties:
+- "regulator-name"

+Optional regulator properties:

+
+When no "regulator-[min|max]-microvolt" properties are defined,
