* Dialog DA9062 Power Management Integrated Circuit (PMIC)
Product information for the DA9062 and DA9061 devices can be found here:
- http://www.dialog-semiconductor.com/products/da9062
- http://www.dialog-semiconductor.com/products/da9061
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
The DA9061 PMIC consists of:
Device Supply Names Description
------ ------------ -----------
da9062-regulator : : LDOs & BUCKs
da9062-onkey : : On Key
da9062-watchdog : : Watchdog Timer
da9062-thermal : : Thermal
======
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
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
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 {
DA9062_BUCK1: buck1 {
regulator-name = "BUCK1";
regulator-min-microvolt = <300000>;
regulator-max-microvolt = <1570000>;
regulator-min-microamp = <500000>;
regulator-max-microamp = <2000000>;
regulator-initial-mode = <DA9063_BUCK_MODE_SYNC>;
regulator-boot-on;
};
DA9062_LDO1: ldo1 {
regulator-name = "LDO_1";
regulator-min-microvolt = <900000>;
regulator-max-microvolt = <3600000>;
regulator-boot-on;
};
};
};
