5Device Supply Names Description
6------ ------------ -----------
7da9062-regulator : : LDOs & BUCKs

13Required 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
23See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt for
24further information on IRQ bindings.
25
26Sub-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

S Twiss2f5532a2015-07-21 11:29:06 +010045- 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
S Twiss922e3c22015-07-01 14:11:33 +010049- 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.
