1* Dialog DA9055 Power Management Integrated Circuit (PMIC) 2 3DA9055 consists of a large and varied group of sub-devices (I2C Only): 4 5Device Supply Names Description 6------ ------------ ----------- 7da9055-gpio : : GPIOs 8da9055-regulator : : Regulators 9da9055-onkey : : On key 10da9055-rtc : : RTC 11da9055-hwmon : : ADC 12da9055-watchdog : : Watchdog 13 14The CODEC device in DA9055 has a separate, configurable I2C address and so 15is instantiated separately from the PMIC. 16 17For details on accompanying CODEC I2C device, see the following: 18Documentation/devicetree/bindings/sound/da9055.txt 19 20====== 21 22Required 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 29Sub-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 44 45 46Example: 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 }; 70 };
