   3 DA9055 consists of a large and varied group of sub-devices (I2C Only):

   5 Device                   Supply Names    Description
   6 ------                   ------------    -----------
   7 da9055-gpio             :               : GPIOs
   8 da9055-regulator        :               : Regulators
   9 da9055-onkey            :               : On key
  10 da9055-rtc              :               : RTC
  11 da9055-hwmon            :               : ADC
  12 da9055-watchdog         :               : Watchdog
  13
  14 The CODEC device in DA9055 has a separate, configurable I2C address and so
  15 is instantiated separately from the PMIC.

  22 Required properties:
  23 - compatible : Should be "dlg,da9055-pmic"
  24 - reg: Specifies the I2C slave address (defaults to 0x5a but can be modified)
  25 - interrupts: IRQ line info for da9055 chip.
  26 - interrupt-controller: da9055 has internal IRQs (has own IRQ domain).
  27 - #interrupt-cells: Should be 1, is the local IRQ number for da9055.
  28
  29 Sub-nodes:
  30 - regulators : Contain the regulator nodes. The DA9055 regulators are
  31   bound using their names as listed below:
  32
  33     buck1     : regulator BUCK1
  34     buck2     : regulator BUCK2
  35     ldo1      : regulator LDO1
  36     ldo2      : regulator LDO2
  37     ldo3      : regulator LDO3
  38     ldo4      : regulator LDO4
  39     ldo5      : regulator LDO5
  40     ldo6      : regulator LDO6
