* Dialog DA9062 Power Management Integrated Circuit (PMIC)
DA9062 consists of a large and varied group of sub-devices:
Device Supply Names Description
------ ------------ -----------
da9062-regulator : : LDOs & BUCKs
da9062-watchdog : : Watchdog Timer
======
Required properties:
- compatible : Should be "dlg,da9062".
- 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.
- 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 component follows the standard regulator framework and the bindings
details of individual regulator device can be found in:
Documentation/devicetree/bindings/regulator/regulator.txt
- watchdog: This node defines the settings for the watchdog driver associated
with the DA9062 PMIC. The compatible = "dlg,da9062-watchdog" should be added
if a node is created.
Example:
pmic0: da9062@58 {
compatible = "dlg,da9062";
reg = <0x58>;
interrupt-parent = <&gpio6>;
interrupts = <11 IRQ_TYPE_LEVEL_LOW>;
interrupt-controller;
watchdog {
compatible = "dlg,da9062-watchdog";
};
regulators {
DA9062_BUCK1: buck1 {
regulator-name = "BUCK1";
regulator-min-microvolt = <300000>;
regulator-max-microvolt = <1570000>;
regulator-min-microamp = <500000>;
regulator-max-microamp = <2000000>;
regulator-boot-on;
};
DA9062_LDO1: ldo1 {
regulator-name = "LDO_1";
regulator-min-microvolt = <900000>;
regulator-max-microvolt = <3600000>;
regulator-boot-on;
};
};
};
