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).
|
|
- interrupt-parent : Specifies the reference to the interrupt controller for
|
|
the DA9062 or DA9061.
|
|
- 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
