+Binding for Maxim MAX77802 regulators
+
+This is a part of device tree bindings of MAX77802 multi-function device.
+More information can be found in bindings/mfd/max77802.txt file.
+
+The MAX77802 PMIC has 10 high-efficiency Buck and 32 Low-dropout (LDO)
+regulators that can be controlled over I2C.
+
+Following properties should be present in main device node of the MFD chip.
+
+Optional properties:
+- inb1-supply: The input supply for BUCK1
+- inb2-supply: The input supply for BUCK2
+- inb3-supply: The input supply for BUCK3
+- inb4-supply: The input supply for BUCK4
+- inb5-supply: The input supply for BUCK5
+- inb6-supply: The input supply for BUCK6
+- inb7-supply: The input supply for BUCK7
+- inb8-supply: The input supply for BUCK8
+- inb9-supply: The input supply for BUCK9
+- inb10-supply: The input supply for BUCK10
+- inl1-supply: The input supply for LDO8 and LDO15
+- inl2-supply: The input supply for LDO17, LDO27, LDO30 and LDO35
+- inl3-supply: The input supply for LDO3, LDO5, LDO6 and LDO7
+- inl4-supply: The input supply for LDO10, LDO11, LDO13 and LDO14
+- inl5-supply: The input supply for LDO9 and LDO19
+- inl6-supply: The input supply for LDO4, LDO21, LDO24 and LDO33
+- inl7-supply: The input supply for LDO18, LDO20, LDO28 and LDO29
+- inl9-supply: The input supply for LDO12, LDO23, LDO25, LDO26, LDO32 and LDO34
+- inl10-supply: The input supply for LDO1 and LDO2
+
+Optional nodes:
+- regulators : The regulators of max77802 have to be instantiated
+ under subnode named "regulators" using the following format.
+
+ regulator-name {
+ standard regulator constraints....
+ };
+ refer Documentation/devicetree/bindings/regulator/regulator.txt
+
+The regulator node name should be initialized with a string to get matched
+with their hardware counterparts as follow. The valid names are:
+
+ -LDOn : for LDOs, where n can lie in ranges 1-15, 17-21, 23-30
+ and 32-35.
+ example: LDO1, LDO2, LDO35.
+ -BUCKn : for BUCKs, where n can lie in range 1 to 10.
+ example: BUCK1, BUCK5, BUCK10.
+
+The max77802 regulator supports two different operating modes: Normal and Low
+Power Mode. Some regulators support the modes to be changed at startup or by
+the consumers during normal operation while others only support to change the
+mode during system suspend. The standard regulator suspend states binding can
+be used to configure the regulator operating mode.
+
+The regulators that support the standard "regulator-initial-mode" property,
+changing their mode during normal operation are: LDOs 1, 3, 20 and 21.
+
+The possible values for "regulator-initial-mode" and "regulator-mode" are:
+ 1: Normal regulator voltage output mode.
+ 3: Low Power which reduces the quiescent current down to only 1uA
+
+The valid modes list is defined in the dt-bindings/regulator/maxim,max77802.h
+header and can be included by device tree source files.
+
+The standard "regulator-mode" property can only be used for regulators that
+support changing their mode to Low Power Mode during suspend. These regulators
+are: BUCKs 2-4 and LDOs 1-35. Also, it only takes effect if the regulator has
+been enabled for the given suspend state using "regulator-on-in-suspend" and
+has not been disabled for that state using "regulator-off-in-suspend".
+
+Example:
+
+ max77802@9 {
+ compatible = "maxim,max77802";
+ interrupt-parent = <&wakeup_eint>;
+ interrupts = <26 0>;
+ reg = <0x09>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ inb1-supply = <&parent_reg>;
