x-powers,axp192-regulator

Vendor: X-Powers

Note

An implementation of a driver matching this compatible is available in drivers/regulator/regulator_axp192.c.

Description

AXP192 PMIC

The PMIC has three DCDC converters and two LDOs (LDO1 cannot be disabled).
All need to be defined as children nodes.
For example:

i2c {
  pmic@34 {
    reg = <0x34>;
    ...
    regulators {
      compatible = "x-powers,axp192-regulator";

      DCDC1 {
        /* all properties for DCDC1 */
      };
      DCDC2 {
        /* all properties for DCDC2 */
      };
      DCDC3 {
        /* all properties for DCDC3 */
      };
      LDOIO0 {
        /* all properties for LDOIO0 */
      };
      LDO2 {
        /* all properties for LDO2 */
      };
      LDO3 {
        /* all properties for LDO3 */
      };
    };
  };
};

Properties

Top level properties

These property descriptions apply to “x-powers,axp192-regulator” nodes themselves. This page also describes child node properties in the following sections.

Node specific properties

Properties not inherited from the base binding file.

(None)

Deprecated node specific properties

Deprecated properties not inherited from the base binding file.

(None)

Base properties

Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “x-powers,axp192-regulator” compatible.

Name

Type

Details

status

string

 
indicates the operational status of a device

Legal values: 'ok', 'okay', 'disabled', 'reserved', 'fail', 'fail-sss'

See Important properties for more information.

compatible

string-array

 
compatible strings

This property is required.

See Important properties for more information.

reg

array

 
register space

See Important properties for more information.

reg-names

string-array

 
name of each register space

interrupts

array

 
interrupts for device

See Important properties for more information.

interrupts-extended

compound

 
extended interrupt specifier for device

interrupt-names

string-array

 
name of each interrupt

interrupt-parent

phandle

 
phandle to interrupt controller node

label

string

 
Human readable string describing the device (used as device_get_binding() argument)

See Important properties for more information.

This property is deprecated.

clocks

phandle-array

 
Clock gate information

clock-names

string-array

 
name of each clock

#address-cells

int

 
number of address cells in reg property

#size-cells

int

 
number of size cells in reg property

dmas

phandle-array

 
DMA channels specifiers

dma-names

string-array

 
Provided names of DMA channel specifiers

io-channels

phandle-array

 
IO channels specifiers

io-channel-names

string-array

 
Provided names of IO channel specifiers

mboxes

phandle-array

 
mailbox / IPM channels specifiers

mbox-names

string-array

 
Provided names of mailbox / IPM channel specifiers

power-domains

phandle-array

 
Power domain specifiers

power-domain-names

string-array

 
Provided names of power domain specifiers

#power-domain-cells

int

 
Number of cells in power-domains property

zephyr,deferred-init

boolean

 
Do not initialize device automatically on boot. Device should be manually
initialized using device_init().

wakeup-source

boolean

 
Property to identify that a device can be used as wake up source.

When this property is provided a specific flag is set into the
device that tells the system that the device is capable of
wake up the system.

Wake up capable devices are disabled (interruptions will not wake up
the system) by default but they can be enabled at runtime if necessary.

zephyr,pm-device-runtime-auto

boolean

 
Automatically configure the device for runtime power management after the
init function runs.

zephyr,disabling-power-states

phandles

 
List of power states that will disable this device power.

Child node properties

Name

Type

Details

regulator-initial-mode

int

 
Initial operating mode. AXP192 supports 2 different power modes:
AXP192_DCDC_MODE_AUTO: Auto (0, default)
AXP192_DCDC_MODE_PWM:  PWM

Legal values: 0, 1

regulator-init-microvolt

int

 
Voltage set during initialisation

regulator-min-microvolt

int

 
smallest voltage consumers may set

regulator-max-microvolt

int

 
largest voltage consumers may set

regulator-always-on

boolean

 
boolean, regulator should never be disabled

regulator-boot-on

boolean

 
bootloader/firmware enabled regulator.
It's expected that this regulator was left on by the bootloader.
If the bootloader didn't leave it on then OS should turn it on
at boot but shouldn't prevent it from being turned off later.
This property is intended to only be used for regulators where
software cannot read the state of the regulator.

regulator-boot-off

boolean

 
Regulator should be disabled on boot.

regulator-allowed-modes

array

 
List of operating modes that software is allowed to configure for the
regulator at run-time. Elements may be specified in any order. The set of
possible operating modes depends on the capabilities of every hardware so
each device binding document explains which values the regulator supports.
