1 | * Dialog DA9062 Power Management Integrated Circuit (PMIC) |
2 | ||
3 | DA9062 consists of a large and varied group of sub-devices: | |
4 | ||
5 | Device Supply Names Description | |
6 | ------ ------------ ----------- | |
7 | da9062-regulator : : LDOs & BUCKs | |
2f5532a2 | 8 | da9062-rtc : : Real-Time Clock |
922e3c22 T |
9 | da9062-watchdog : : Watchdog Timer |
10 | ||
11 | ====== | |
12 | ||
13 | Required properties: | |
14 | ||
15 | - compatible : Should be "dlg,da9062". | |
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 DA9062. | |
20 | - interrupts : IRQ line information. | |
21 | - interrupt-controller | |
22 | ||
23 | See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt for | |
24 | further information on IRQ bindings. | |
25 | ||
26 | Sub-nodes: | |
27 | ||
28 | - regulators : This node defines the settings for the LDOs and BUCKs. The | |
29 | DA9062 regulators are bound using their names listed below: | |
30 | ||
31 | buck1 : BUCK_1 | |
32 | buck2 : BUCK_2 | |
33 | buck3 : BUCK_3 | |
34 | buck4 : BUCK_4 | |
35 | ldo1 : LDO_1 | |
36 | ldo2 : LDO_2 | |
37 | ldo3 : LDO_3 | |
38 | ldo4 : LDO_4 | |
39 | ||
40 | The component follows the standard regulator framework and the bindings | |
41 | details of individual regulator device can be found in: | |
42 | Documentation/devicetree/bindings/regulator/regulator.txt | |

45 | - rtc : This node defines settings required for the Real-Time Clock associated |
46 | with the DA9062. There are currently no entries in this binding, however | |
47 | compatible = "dlg,da9062-rtc" should be added if a node is created. | |
48 | ||
922e3c22 T |
49 | - watchdog: This node defines the settings for the watchdog driver associated |
50 | with the DA9062 PMIC. The compatible = "dlg,da9062-watchdog" should be added | |
51 | if a node is created. | |
52 | ||
53 | ||
54 | Example: | |
55 | ||
56 | pmic0: da9062@58 { | |
57 | compatible = "dlg,da9062"; | |
58 | reg = <0x58>; | |
59 | interrupt-parent = <&gpio6>; | |
60 | interrupts = <11 IRQ_TYPE_LEVEL_LOW>; | |
61 | interrupt-controller; | |
62 | ||
2f5532a2 T |
63 | rtc { |
64 | compatible = "dlg,da9062-rtc"; | |
65 | }; | |
66 | ||
922e3c22 T |
67 | watchdog { |
68 | compatible = "dlg,da9062-watchdog"; | |
69 | }; | |
