* Dialog DA9063 Power Management Integrated Circuit (PMIC)
DA9093 consists of a large and varied group of sub-devices (I2C Only):
Device Supply Names Description
------ ------------ -----------
da9063-regulator : : LDOs & BUCKs
da9063-onkey : : On Key
da9063-rtc : : Real-Time Clock
da9063-watchdog : : Watchdog
======
Required properties:
- compatible : Should be "dlg,da9063"
- 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 DA9063.
- interrupts : IRQ line information.
- interrupt-controller
Sub-nodes:
- regulators : This node defines the settings for the LDOs and BUCKs. The
DA9063 regulators are bound using their names listed below:
bcore1 : BUCK CORE1
bcore2 : BUCK CORE2
bpro : BUCK PRO
bmem : BUCK MEM
bio : BUCK IO
bperi : BUCK PERI
ldo1 : LDO_1
ldo2 : LDO_2
ldo3 : LDO_3
ldo4 : LDO_4
ldo5 : LDO_5
ldo6 : LDO_6
ldo7 : LDO_7
ldo8 : LDO_8
ldo9 : LDO_9
ldo10 : LDO_10
ldo11 : LDO_11
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 for the Real-Time Clock associated with
the DA9063. There are currently no entries in this binding, however
compatible = "dlg,da9063-rtc" should be added if a node is created.
- onkey : This node defines the OnKey settings for controlling the key
functionality of the device. The node should contain the compatible property
with the value "dlg,da9063-onkey".
Optional onkey properties:
- dlg,disable-key-power : Disable power-down using a long key-press. If this
entry exists the OnKey driver will remove support for the KEY_POWER key
press. If this entry does not exist then by default the key-press
triggered power down is enabled and the OnKey will support both KEY_POWER
and KEY_SLEEP.
- watchdog : This node defines settings for the Watchdog timer associated
with the DA9063. There are currently no entries in this binding, however
compatible = "dlg,da9063-watchdog" should be added if a node is created.
Example:
pmic0: da9063@58 {
compatible = "dlg,da9063"
reg = <0x58>;
interrupt-parent = <&gpio6>;
interrupts = <11 IRQ_TYPE_LEVEL_LOW>;
interrupt-controller;
rtc {
compatible = "dlg,da9063-rtc";
};
wdt {
compatible = "dlg,da9063-watchdog";
};
onkey {
compatible = "dlg,da9063-onkey";
dlg,disable-key-power;
};
regulators {
DA9063_BCORE1: bcore1 {
regulator-name = "BCORE1";
regulator-min-microvolt = <300000>;
regulator-max-microvolt = <1570000>;
regulator-min-microamp = <500000>;
regulator-max-microamp = <2000000>;
regulator-boot-on;
};
DA9063_LDO11: ldo11 {
regulator-name = "LDO_11";
regulator-min-microvolt = <900000>;
regulator-max-microvolt = <3600000>;
regulator-boot-on;
};
};
};
