   1 Maxim MAX77693 multi-function device
   2
   3 MAX77693 is a Multifunction device with the following submodules:
   4 - PMIC,
   5 - CHARGER,
   6 - LED,
   7 - MUIC,
   8 - HAPTIC
   9
  10 It is interfaced to host controller using i2c.
  11 This document describes the bindings for the mfd device.

  13 Required properties:
  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.
  18
  19 Optional properties:
  20 - regulators : The regulators of max77693 have to be instantiated under subnod
  21   named "regulators" using the following format.
