+Binding for Maxim MAX77686 regulators
+
+This is a part of the device tree bindings of MAX77686 multi-function device.
+More information can be found in ../mfd/max77686.txt file.
+
+The MAX77686 PMIC has 9 high-efficiency Buck and 26 Low-DropOut (LDO)
+regulators that can be controlled over I2C.
+
+Following properties should be present in main device node of the MFD chip.
+
+Optional node:
+- voltage-regulators : The regulators of max77686 have to be instantiated
+  under subnode named "voltage-regulators" using the following format.
+
+	regulator_name {
+		regulator-compatible = LDOn/BUCKn
+		standard regulator constraints....
+	};
+	refer Documentation/devicetree/bindings/regulator/regulator.txt
+
+  The regulator node's name should be initialized with a string
+to get matched with their hardware counterparts as follow:
+
+	-LDOn 	:	for LDOs, where n can lie in range 1 to 26.
+			example: LDO1, LDO2, LDO26.
+	-BUCKn 	:	for BUCKs, where n can lie in range 1 to 9.
+			example: BUCK1, BUCK5, BUCK9.
+
+  Regulators which can be turned off during system suspend:
+	-LDOn	:	2, 6-8, 10-12, 14-16,
+	-BUCKn	:	1-4.
+  Use standard regulator bindings for it ('regulator-off-in-suspend').
+
+  LDO20, LDO21, LDO22, BUCK8 and BUCK9 can be configured to GPIO enable
+  control. To turn this feature on this property must be added to the regulator
+  sub-node:
+	- maxim,ena-gpios :	one GPIO specifier enable control (the gpio
+				flags are actually ignored and always
+				ACTIVE_HIGH is used)

-pwm regulator bindings
+Bindings for the Generic PWM Regulator
+======================================
+
+Currently supports 2 modes of operation:
+
+Voltage Table:		When in this mode, a voltage table (See below) of
+			predefined voltage <=> duty-cycle values must be
+			provided via DT. Limitations are that the regulator can
+			only operate at the voltages supplied in the table.
+			Intermediary duty-cycle values which would normally
+			allow finer grained voltage selection are ignored and
+			rendered useless.  Although more control is given to
+			the user if the assumptions made in continuous-voltage
+			mode do not reign true.
+
+Continuous Voltage:	This mode uses the regulator's maximum and minimum
+			supplied voltages specified in the
+			regulator-{min,max}-microvolt properties to calculate
+			appropriate duty-cycle values.  This allows for a much
+			more fine grained solution when compared with
+			voltage-table mode above.  This solution does make an
+			assumption that a %50 duty-cycle value will cause the
+			regulator voltage to run at half way between the
+			supplied max_uV and min_uV values.
 
 Required properties:
-- compatible: Should be "pwm-regulator"
-- pwms: OF device-tree PWM specification (see PWM binding pwm.txt)
-- voltage-table: voltage and duty table, include 2 members in each set of
-  brackets, first one is voltage(unit: uv), the next is duty(unit: percent)
+--------------------
+- compatible:		Should be "pwm-regulator"
+
+- pwms:			PWM specification (See: ../pwm/pwm.txt)
+
+Only required for Voltage Table Mode:
+- voltage-table: 	Voltage and Duty-Cycle table consisting of 2 cells
+			    First cell is voltage in microvolts (uV)
+			    Second cell is duty-cycle in percent (%)
+
+NB: To be clear, if voltage-table is provided, then the device will be used
+in Voltage Table Mode.  If no voltage-table is provided, then the device will
+be used in Continuous Voltage Mode.
