1* Dialog DA9063 Power Management Integrated Circuit (PMIC)
2
3DA9093 consists of a large and varied group of sub-devices (I2C Only):
4
5Device Supply Names Description
6------ ------------ -----------
7da9063-regulator : : LDOs & BUCKs
8da9063-rtc : : Real-Time Clock
9da9063-watchdog : : Watchdog

13Required properties:
14
15- compatible : Should be "dlg,da9063"
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 DA9063.
20- interrupts : IRQ line information.
21- interrupt-controller
22
23Sub-nodes:
24
25- regulators : This node defines the settings for the LDOs and BUCKs. The
26 DA9063 regulators are bound using their names listed below:
27
28 bcore1 : BUCK CORE1
29 bcore2 : BUCK CORE2
30 bpro : BUCK PRO
31 bmem : BUCK MEM
32 bio : BUCK IO
33 bperi : BUCK PERI
34 ldo1 : LDO_1
35 ldo2 : LDO_2
36 ldo3 : LDO_3
37 ldo4 : LDO_4
38 ldo5 : LDO_5
39 ldo6 : LDO_6
40 ldo7 : LDO_7
41 ldo8 : LDO_8
42 ldo9 : LDO_9
43 ldo10 : LDO_10
44 ldo11 : LDO_11
45
46 The component follows the standard regulator framework and the bindings
47 details of individual regulator device can be found in:
48 Documentation/devicetree/bindings/regulator/regulator.txt
49
50- rtc : This node defines settings for the Real-Time Clock associated with
51 the DA9063. There are currently no entries in this binding, however
52 compatible = "dlg,da9063-rtc" should be added if a node is created.
53
54- watchdog : This node defines settings for the Watchdog timer associated
55 with the DA9063. There are currently no entries in this binding, however
56 compatible = "dlg,da9063-watchdog" should be added if a node is created.
