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 Description6------ ------------ -----------7da9055-gpio : : GPIOs8da9055-regulator : : Regulators9da9055-onkey : : On key10da9055-rtc : : RTC11da9055-hwmon : : ADC12da9055-watchdog : : Watchdog13 14The CODEC device in DA9055 has a separate, configurable I2C address and so15is instantiated separately from the PMIC.16 17For details on accompanying CODEC I2C device, see the following:18Documentation/devicetree/bindings/sound/da9055.txt19 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.
