28Required 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
40See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt for
41further information on IRQ bindings.
42
43Sub-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
