1 * Dialog DA9055 Power Management Integrated Circuit (PMIC)
2
3 DA9055 consists of a large and varied group of sub-devices (I2C Only):
4
5 Device Supply Names Description
6 ------ ------------ -----------
7 da9055-gpio : : GPIOs
8 da9055-regulator : : Regulators
9 da9055-onkey : : On key
10 da9055-rtc : : RTC
11 da9055-hwmon : : ADC
12 da9055-watchdog : : Watchdog
13
14 The CODEC device in DA9055 has a separate, configurable I2C address and so
15 is instantiated separately from the PMIC.
16
17 For details on accompanying CODEC I2C device, see the following:

22 Required properties:
23 - compatible : Should be "dlg,da9055-pmic"
24 - reg: Specifies the I2C slave address (defaults to 0x5a but can be modified)
25 - interrupts: IRQ line info for da9055 chip.
26 - interrupt-controller: da9055 has internal IRQs (has own IRQ domain).
27 - #interrupt-cells: Should be 1, is the local IRQ number for da9055.
28
29 Sub-nodes:
30 - regulators : Contain the regulator nodes. The DA9055 regulators are
31 bound using their names as listed below:
32
33 buck1 : regulator BUCK1
34 buck2 : regulator BUCK2
35 ldo1 : regulator LDO1
36 ldo2 : regulator LDO2
37 ldo3 : regulator LDO3
38 ldo4 : regulator LDO4
39 ldo5 : regulator LDO5
40 ldo6 : regulator LDO6
