Required properties:
|
|
- compatible : Should be
|
"dlg,da9062" for DA9062
|
"dlg,da9061" for DA9061
|
- reg : Specifies the I2C slave address (this defaults to 0x58 but it can be
|
modified to match the chip's OTP settings).
|
- interrupts : IRQ line information.
|
- interrupt-controller
|
|
See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt for
|
further information on IRQ bindings.
|
|
Sub-nodes:
|
|
- regulators : This node defines the settings for the LDOs and BUCKs.
|
The DA9062 regulators are bound using their names listed below:
|
|
buck1 : BUCK_1
|
buck2 : BUCK_2
|
buck3 : BUCK_3
|
buck4 : BUCK_4
|
ldo1 : LDO_1
|
ldo2 : LDO_2
|
ldo3 : LDO_3
|
ldo4 : LDO_4
|
|
The DA9061 regulators are bound using their names listed below:
|
|
buck1 : BUCK_1
|
buck2 : BUCK_2
|
buck3 : BUCK_3
|
ldo1 : LDO_1
|
ldo2 : LDO_2
|
ldo3 : LDO_3
|
ldo4 : LDO_4
|
|
The component follows the standard regulator framework and the bindings
|
details of individual regulator device can be found in:
|
Documentation/devicetree/bindings/regulator/regulator.txt
|
|
- rtc : This node defines settings required for the Real-Time Clock associated
|
with the DA9062. There are currently no entries in this binding, however
|
compatible = "dlg,da9062-rtc" should be added if a node is created.
|
|
- onkey : See ../input/da9062-onkey.txt
|
|
- watchdog: See ../watchdog/da9062-watchdog.txt
|
|
- thermal : See ../thermal/da9062-thermal.txt
|
|
Example:
|
|
pmic0: da9062@58 {
|
compatible = "dlg,da9062";
|
reg = <0x58>;
|
interrupt-parent = <&gpio6>;
|
interrupts = <11 IRQ_TYPE_LEVEL_LOW>;
|
interrupt-controller;
|
|
rtc {
|
compatible = "dlg,da9062-rtc";
|
};
|
|
regulators {

|
regulator-min-microamp = <500000>;
|
regulator-max-microamp = <2000000>;
