should be used, which is intended to be used
by Co-Processors (e.g. a modem).
Example:
&twl {
madc {
compatible = "ti,twl4030-madc";
interrupts = <3>;
#io-channel-cells = <1>;

* 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)
- 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
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>;

This driver provides support for Triton TWL4030-MADC. The
driver supports both RT and SW conversion methods.
This driver can also be built as a module. If so, the module will be
