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: | |
| 18 | Documentation/devicetree/bindings/sound/da9055.txt | |
| 19 | ||
| 20 | ====== | |
| 21 | ||
| 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 | - interrupt-parent: Specifies the phandle of the interrupt controller to which | |
| 26 | the IRQs from da9055 are delivered to. | |
| 27 | - interrupts: IRQ line info for da9055 chip. | |
| 28 | - interrupt-controller: da9055 has internal IRQs (has own IRQ domain). | |
| 29 | - #interrupt-cells: Should be 1, is the local IRQ number for da9055. | |
| 30 | ||
| 31 | Sub-nodes: | |
| 32 | - regulators : Contain the regulator nodes. The DA9055 regulators are | |
| 33 | bound using their names as listed below: | |
| 34 | ||
| 35 | buck1 : regulator BUCK1 | |
| 36 | buck2 : regulator BUCK2 | |
| 37 | ldo1 : regulator LDO1 | |
| 38 | ldo2 : regulator LDO2 | |
| 39 | ldo3 : regulator LDO3 | |
| 40 | ldo4 : regulator LDO4 | |
| 41 | ldo5 : regulator LDO5 | |
| 42 | ldo6 : regulator LDO6 | |
| 43 | ||
| 44 | The bindings details of individual regulator device can be found in: | |
| 45 | Documentation/devicetree/bindings/regulator/regulator.txt | |
| 46 | ||

| 48 | Example: | |
| 49 | ||
| 50 | pmic: da9055-pmic@5a { | |
| 51 | compatible = "dlg,da9055-pmic"; | |
| 52 | reg = <0x5a>; | |
| 53 | interrupt-parent = <&intc>; | |
| 54 | interrupts = <5 IRQ_TYPE_LEVEL_LOW>; | |
| 55 | interrupt-controller; | |
| 56 | #interrupt-cells = <1>; | |
| 57 | ||
| 58 | regulators { | |
| 59 | buck1: BUCK1 { | |
| 60 | regulator-min-microvolt = <725000>; | |
| 61 | regulator-max-microvolt = <2075000>; | |
| 62 | }; | |
| 63 | buck2: BUCK2 { | |
| 64 | regulator-min-microvolt = <925000>; | |
| 65 | regulator-max-microvolt = <2500000>; | |
| 66 | }; | |
| 67 | ldo1: LDO1 { | |
| 68 | regulator-min-microvolt = <900000>; | |
| 69 | regulator-max-microvolt = <3300000>; | |
| 70 | }; | |
| 71 | }; | |
