| * 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: |
| Documentation/devicetree/bindings/regulator/regulator.txt |
| |
| |
| 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>; |
| |
| regulators { |
| buck1: BUCK1 { |
| regulator-min-microvolt = <725000>; |
| regulator-max-microvolt = <2075000>; |
| }; |
| buck2: BUCK2 { |
| regulator-min-microvolt = <925000>; |
| regulator-max-microvolt = <2500000>; |
| }; |
| ldo1: LDO1 { |
| regulator-min-microvolt = <900000>; |
| regulator-max-microvolt = <3300000>; |
| }; |
| }; |
| }; |
