* 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:

|
======
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible : Should be "dlg,da9055-pmic"
|
||
|
|
- reg: Specifies the I2C slave address (defaults to 0x5a but can be modified)
|
||
|
|
- interrupt-parent: Specifies the phandle of the interrupt controller to which
|
||
|
|
the IRQs from da9055 are delivered to.
|
||
|
|
- 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
|
||
|
|
|
||
|
|
