+- 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 approprite level of feedback.
+
+ Required properties:
+	- compatible : Must be "maxim,max77693-hpatic"
+	- 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 informations, please refer to documentaion.
