* 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>; }; }; }; |
