| 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 | - 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 |
| 41 | |
| 42 | The bindings details of individual regulator device can be found in: |
| 43 | Documentation/devicetree/bindings/regulator/regulator.txt |

| 45 | |
| 46 | Example: |
| 47 | |
| 48 | pmic: da9055-pmic@5a { |
| 49 | compatible = "dlg,da9055-pmic"; |
| 50 | reg = <0x5a>; |
| 51 | interrupt-parent = <&intc>; |
| 52 | interrupts = <5 IRQ_TYPE_LEVEL_LOW>; |
| 53 | interrupt-controller; |
| 54 | #interrupt-cells = <1>; |
| 55 | |
| 56 | regulators { |
| 57 | buck1: BUCK1 { |
| 58 | regulator-min-microvolt = <725000>; |
| 59 | regulator-max-microvolt = <2075000>; |
| 60 | }; |
| 61 | buck2: BUCK2 { |
| 62 | regulator-min-microvolt = <925000>; |
| 63 | regulator-max-microvolt = <2500000>; |
| 64 | }; |
| 65 | ldo1: LDO1 { |
| 66 | regulator-min-microvolt = <900000>; |
| 67 | regulator-max-microvolt = <3300000>; |
| 68 | }; |
| 69 | }; |
