-
-MAX77693 is a Multifunction device with the following submodules:
-- PMIC,
-- CHARGER,
-- LED,
-- MUIC,
-- HAPTIC
-
-It is interfaced to host controller using i2c.
-This document describes the bindings for the mfd device.
-
-Required properties:
-- compatible : Must be "maxim,max77693".
-- reg : Specifies the i2c slave address of PMIC block.
-- interrupts : This i2c device has an IRQ line connected to the main SoC.
-
-Optional properties:
-- regulators : The regulators of max77693 have to be instantiated under subnode
-  named "regulators" using the following format.
-
-	regulators {
-		regulator-compatible = ESAFEOUT1/ESAFEOUT2/CHARGER
-		standard regulator constraints[*].
-	};
-
-	[*] refer Documentation/devicetree/bindings/regulator/regulator.txt
-
-- haptic : The MAX77693 haptic device utilises a PWM controlled motor to provide
-  users with tactile feedback. PWM period and duty-cycle are varied in
-  order to provide the appropriate level of feedback.
-
- Required properties:
-	- compatible : Must be "maxim,max77693-haptic"
-	- haptic-supply : power supply for the haptic motor
-	[*] refer Documentation/devicetree/bindings/regulator/regulator.txt
-	- pwms : phandle to the physical PWM(Pulse Width Modulation) device.
-	 PWM properties should be named "pwms". And number of cell is different
-	 for each pwm device.
-	 To get more information, please refer to documentation.
-	[*] refer Documentation/devicetree/bindings/pwm/pwm.txt
-
-- charger : Node configuring the charger driver.
-  If present, required properties:
-  - compatible : Must be "maxim,max77693-charger".
-
-  Optional properties (if not set, defaults will be used):
-  - maxim,constant-microvolt : Battery constant voltage in uV. The charger
-    will operate in fast charge constant current mode till battery voltage
-    reaches this level. Then the charger will switch to fast charge constant
-    voltage mode. Also vsys (system voltage) will be set to this value when
-    DC power is supplied but charger is not enabled.

-    Default: 3500000
-
-  - maxim,charge-input-threshold-microvolt : Threshold voltage in uV for
