   3 DA9062 consists of a large and varied group of sub-devices:
   4
   5 Device                   Supply Names    Description
   6 ------                   ------------    -----------
   7 da9062-regulator        :               : LDOs & BUCKs

  13 Required properties:
  14
  15 - compatible : Should be "dlg,da9062".
  16 - reg : Specifies the I2C slave address (this defaults to 0x58 but it can be
  17   modified to match the chip's OTP settings).
  18 - interrupt-parent : Specifies the reference to the interrupt controller for
  19   the DA9062.
  20 - interrupts : IRQ line information.
  21 - interrupt-controller
  22
  23 See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt for
  24 further information on IRQ bindings.
  25
  26 Sub-nodes:
  27
  28 - regulators : This node defines the settings for the LDOs and BUCKs. The
  29   DA9062 regulators are bound using their names listed below:
  30
  31     buck1    : BUCK_1
  32     buck2    : BUCK_2
  33     buck3    : BUCK_3
  34     buck4    : BUCK_4
  35     ldo1     : LDO_1
  36     ldo2     : LDO_2
  37     ldo3     : LDO_3
  38     ldo4     : LDO_4
  39
  40   The component follows the standard regulator framework and the bindings
  41   details of individual regulator device can be found in:
  42   Documentation/devicetree/bindings/regulator/regulator.txt
  43
  44
  45 - rtc : This node defines settings required for the Real-Time Clock associated
  46   with the DA9062. There are currently no entries in this binding, however
  47   compatible = "dlg,da9062-rtc" should be added if a node is created.
  48
  49 - watchdog: This node defines the settings for the watchdog driver associated
  50   with the DA9062 PMIC. The compatible = "dlg,da9062-watchdog" should be added
  51   if a node is created.
