3DA9063 consists of a large and varied group of sub-devices (I2C Only):

14Required properties:
15
16- compatible : Should be "dlg,da9063" or "dlg,da9063l"
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- interrupts : IRQ line information.
20- interrupt-controller
21
22Sub-nodes:
23
24- regulators : This node defines the settings for the LDOs and BUCKs.
25  The DA9063(L) regulators are bound using their names listed below:
26
27    bcore1    : BUCK CORE1
28    bcore2    : BUCK CORE2
29    bpro      : BUCK PRO
30    bmem      : BUCK MEM
31    bio       : BUCK IO
32    bperi     : BUCK PERI
33    ldo1      : LDO_1	(DA9063 only)
34    ldo2      : LDO_2	(DA9063 only)
35    ldo3      : LDO_3
36    ldo4      : LDO_4	(DA9063 only)
37    ldo5      : LDO_5	(DA9063 only)
38    ldo6      : LDO_6	(DA9063 only)
39    ldo7      : LDO_7
40    ldo8      : LDO_8
41    ldo9      : LDO_9
42    ldo10     : LDO_10	(DA9063 only)
43    ldo11     : LDO_11
44
45  The component follows the standard regulator framework and the bindings
46  details of individual regulator device can be found in:
47  Documentation/devicetree/bindings/regulator/regulator.txt
48
49- rtc : This node defines settings for the Real-Time Clock associated with
50  the DA9063 only. The RTC is not present in DA9063L. There are currently
51  no entries in this binding, however compatible = "dlg,da9063-rtc" should
52  be added if a node is created.
53
54- onkey : This node defines the OnKey settings for controlling the key
55  functionality of the device. The node should contain the compatible property
56  with the value "dlg,da9063-onkey".
57
58  Optional onkey properties:
59
60  - dlg,disable-key-power : Disable power-down using a long key-press. If this
61    entry exists the OnKey driver will remove support for the KEY_POWER key
62    press. If this entry does not exist then by default the key-press
63    triggered power down is enabled and the OnKey will support both KEY_POWER
64    and KEY_SLEEP.
65
66- watchdog : This node defines settings for the Watchdog timer associated
67  with the DA9063 and DA9063L. The node should contain the compatible property
68  with the value "dlg,da9063-watchdog".
69
70  Optional watchdog properties:
71  - dlg,use-sw-pm: Add this property to disable the watchdog during suspend.
72  Only use this option if you can't use the watchdog automatic suspend
73  function during a suspend (see register CONTROL_B).
