  28 Required properties:
  29
  30 - compatible : Should be
  31     "dlg,da9062" for DA9062
  32     "dlg,da9061" for DA9061
  33 - reg : Specifies the I2C slave address (this defaults to 0x58 but it can be
  34   modified to match the chip's OTP settings).
  35 - interrupt-parent : Specifies the reference to the interrupt controller for
  36   the DA9062 or DA9061.
  37 - interrupts : IRQ line information.
  38 - interrupt-controller
  39
  40 See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt for
  41 further information on IRQ bindings.
  42
  43 Sub-nodes:
  44
  45 - regulators : This node defines the settings for the LDOs and BUCKs.
  46   The DA9062 regulators are bound using their names listed below:
  47
  48     buck1    : BUCK_1
  49     buck2    : BUCK_2
  50     buck3    : BUCK_3
  51     buck4    : BUCK_4
  52     ldo1     : LDO_1
  53     ldo2     : LDO_2
  54     ldo3     : LDO_3
  55     ldo4     : LDO_4
  56
  57   The DA9061 regulators are bound using their names listed below:
  58
  59     buck1    : BUCK_1
  60     buck2    : BUCK_2
  61     buck3    : BUCK_3
  62     ldo1     : LDO_1
  63     ldo2     : LDO_2
  64     ldo3     : LDO_3
  65     ldo4     : LDO_4
  66
  67   The component follows the standard regulator framework and the bindings
  68   details of individual regulator device can be found in:
  69   Documentation/devicetree/bindings/regulator/regulator.txt
  70
  71 - rtc : This node defines settings required for the Real-Time Clock associated
  72   with the DA9062. There are currently no entries in this binding, however
  73   compatible = "dlg,da9062-rtc" should be added if a node is created.
  74
  75 - onkey : See ../input/da9062-onkey.txt
  76
  77 - watchdog: See ../watchdog/da9062-watchdog.txt
  78
  79 - thermal : See ../thermal/da9062-thermal.txt
