1 Maxim MAX77693 multi-function device
3 MAX77693 is a Multifunction device with the following submodules:
10 It is interfaced to host controller using i2c.
11 This document describes the bindings for the mfd device.
14 - compatible : Must be "maxim,max77693".
15 - reg : Specifies the i2c slave address of PMIC block.
16 - interrupts : This i2c device has an IRQ line connected to the main SoC.
17 - interrupt-parent : The parent interrupt controller.
20 - regulators : The regulators of max77693 have to be instantiated under subnod
21 named "regulators" using the following format.
24 regualtor-compatible = ESAFEOUT1/ESAFEOUT2/CHARGER
25 standard regulator constratints[*].
28 [*] refer Documentation/devicetree/bindings/regulator/regulator.txt
30 - haptic : The MAX77693 haptic device utilises a PWM controlled motor to provide
31 users with tactile feedback. PWM period and duty-cycle are varied in
32 order to provide the approprite level of feedback.
35 - compatible : Must be "maxim,max77693-hpatic"
36 - haptic-supply : power supply for the haptic motor
37 [*] refer Documentation/devicetree/bindings/regulator/regulator.txt
38 - pwms : phandle to the physical PWM(Pulse Width Modulation) device.
39 PWM properties should be named "pwms". And number of cell is different
41 To get more informations, please refer to documentaion.
