   3 DA9093 consists of a large and varied group of sub-devices (I2C Only):

   5 Device                   Supply Names    Description
   6 ------                   ------------    -----------
   7 da9063-regulator        :               : LDOs & BUCKs
   8 da9063-onkey            :               : On Key
   9 da9063-rtc              :               : Real-Time Clock

  12 ======
  13
  14 Required properties:
  15
  16 - compatible : Should be "dlg,da9063"
  17 - reg : Specifies the I2C slave address (this defaults to 0x58 but it can be
  18   modified to match the chip's OTP settings).
  19 - interrupt-parent : Specifies the reference to the interrupt controller for
  20   the DA9063.
  21 - interrupts : IRQ line information.
  22 - interrupt-controller
  23
  24 Sub-nodes:
  25
  26 - regulators : This node defines the settings for the LDOs and BUCKs. The
  27   DA9063 regulators are bound using their names listed below:
  28
  29     bcore1    : BUCK CORE1
  30     bcore2    : BUCK CORE2
  31     bpro      : BUCK PRO
  32     bmem      : BUCK MEM
  33     bio       : BUCK IO
  34     bperi     : BUCK PERI
  35     ldo1      : LDO_1
  36     ldo2      : LDO_2
  37     ldo3      : LDO_3
  38     ldo4      : LDO_4
  39     ldo5      : LDO_5
  40     ldo6      : LDO_6
  41     ldo7      : LDO_7
  42     ldo8      : LDO_8
  43     ldo9      : LDO_9
  44     ldo10     : LDO_10
  45     ldo11     : LDO_11
  46
  47   The component follows the standard regulator framework and the bindings
  48   details of individual regulator device can be found in:
  49   Documentation/devicetree/bindings/regulator/regulator.txt
  50
  51 - rtc : This node defines settings for the Real-Time Clock associated with
  52   the DA9063. There are currently no entries in this binding, however
  53   compatible = "dlg,da9063-rtc" should be added if a node is created.
  54
  55 - onkey : This node defines the OnKey settings for controlling the key
  56   functionality of the device. The node should contain the compatible property
  57   with the value "dlg,da9063-onkey".
  58
  59   Optional onkey properties:
  60
  61   - dlg,disable-key-power : Disable power-down using a long key-press. If this
  62     entry exists the OnKey driver will remove support for the KEY_POWER key
  63     press. If this entry does not exist then by default the key-press
  64     triggered power down is enabled and the OnKey will support both KEY_POWER
  65     and KEY_SLEEP.
  66
  67 - watchdog : This node defines settings for the Watchdog timer associated
  68   with the DA9063. There are currently no entries in this binding, however
  69   compatible = "dlg,da9063-watchdog" should be added if a node is created.
