The DA9062 PMIC consists of: |
|
|
|
Device Supply Names Description |
|
------ ------------ ----------- |
|
da9062-regulator : : LDOs & BUCKs |
|
da9062-rtc : : Real-Time Clock |
|
da9062-onkey : : On Key |
|
da9062-watchdog : : Watchdog Timer |
|
da9062-thermal : : Thermal |
|
da9062-gpio : : GPIOs |
|
|
|
The DA9061 PMIC consists of: |
|
|
|
Device Supply Names Description |
|
------ ------------ ----------- |
|
da9062-regulator : : LDOs & BUCKs |
|
da9062-onkey : : On Key |

|
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. |
|
|
|
Optional properties: |
|
|
|
- gpio-controller : Marks the device as a gpio controller. |
|
- #gpio-cells : Should be two. The first cell is the pin number and the |
|
second cell is used to specify the gpio polarity. |
|
|
|
See Documentation/devicetree/bindings/gpio/gpio.txt for further information on |
|
GPIO 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 |
|
|
|
regulator-initial-mode may be specified for buck regulators using mode values |
|
from include/dt-bindings/regulator/dlg,da9063-regulator.h. |
|
|
|
- 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 |
|
|
|

|
