* 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-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.
- 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";
};
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;
};
};

Qualcomm Resource Power Manager (RPM)
This driver is used to interface with the Resource Power Manager (RPM) found in
various Qualcomm platforms. The RPM allows each component in the system to vote
for state of the system resources, such as clocks, regulators and bus
frequencies.
- compatible:
Usage: required
Value type: <string>
Definition: must be one of:
"qcom,rpm-apq8064"
"qcom,rpm-msm8660"
"qcom,rpm-msm8960"
- reg:
Usage: required
Value type: <prop-encoded-array>
Definition: base address and size of the RPM's message ram
- interrupts:
Usage: required
Value type: <prop-encoded-array>
Definition: three entries specifying the RPM's:
1. acknowledgement interrupt
2. error interrupt
3. wakeup interrupt
- interrupt-names:
Usage: required
Value type: <string-array>
Definition: must be the three strings "ack", "err" and "wakeup", in order
- #address-cells:
Usage: required
Value type: <u32>
Definition: must be 1
- #size-cells:
Usage: required
Value type: <u32>
Definition: must be 0
- qcom,ipc:
Usage: required
Value type: <prop-encoded-array>
Definition: three entries specifying the outgoing ipc bit used for
signaling the RPM:
- phandle to a syscon node representing the apcs registers
- u32 representing offset to the register within the syscon
- u32 representing the ipc bit within the register
= EXAMPLE
#include <dt-bindings/mfd/qcom-rpm.h>
rpm@108000 {
compatible = "qcom,rpm-msm8960";
reg = <0x108000 0x1000>;

interrupts = <0 19 0>, <0 21 0>, <0 22 0>;
interrupt-names = "ack", "err", "wakeup";
#address-cells = <1>;
#size-cells = <0>;
