* Dialog DA9055 Power Management Integrated Circuit (PMIC) |
|
|
|
DA9055 consists of a large and varied group of sub-devices (I2C Only): |
|
|
|
Device Supply Names Description |
|
------ ------------ ----------- |
|
da9055-gpio : : GPIOs |
|
da9055-regulator : : Regulators |
|
da9055-onkey : : On key |
|
da9055-rtc : : RTC |
|
da9055-hwmon : : ADC |
|
da9055-watchdog : : Watchdog |
|
|
|
The CODEC device in DA9055 has a separate, configurable I2C address and so |
|
is instantiated separately from the PMIC. |
|
|
|
For details on accompanying CODEC I2C device, see the following: |
|
Documentation/devicetree/bindings/sound/da9055.txt |
|
|
|
====== |
|
|
|
Required properties: |
|
- compatible : Should be "dlg,da9055-pmic" |
|
- reg: Specifies the I2C slave address (defaults to 0x5a but can be modified) |
|
- interrupts: IRQ line info for da9055 chip. |
|
- interrupt-controller: da9055 has internal IRQs (has own IRQ domain). |
|
- #interrupt-cells: Should be 1, is the local IRQ number for da9055. |
|
|
|
Sub-nodes: |
|
- regulators : Contain the regulator nodes. The DA9055 regulators are |
|
bound using their names as listed below: |
|
|
|
buck1 : regulator BUCK1 |
|
buck2 : regulator BUCK2 |
|
ldo1 : regulator LDO1 |
|
ldo2 : regulator LDO2 |
|
ldo3 : regulator LDO3 |
|
ldo4 : regulator LDO4 |
|
ldo5 : regulator LDO5 |
|
ldo6 : regulator LDO6 |
|
|
|
The bindings details of individual regulator device can be found in: |

Example: |
|
|
|
pmic: da9055-pmic@5a { |
|
compatible = "dlg,da9055-pmic"; |
|
reg = <0x5a>; |
|
interrupt-parent = <&intc>; |
|
interrupts = <5 IRQ_TYPE_LEVEL_LOW>; |
|
interrupt-controller; |
|
#interrupt-cells = <1>; |
|
|
|

|
}; |
|
buck2: BUCK2 { |
|
regulator-min-microvolt = <925000>; |
|

|
}; |
|
ldo1: LDO1 { |
|
regulator-min-microvolt = <900000>; |
|
regulator-max-microvolt = <3300000>; |
