regulator-fixed

Vendor: Generic or vendor-independent

Description

GPIO-controlled regulators

Properties

Properties not inherited from the base binding file.

Name

Type

Details

regulator-name

string

Descriptive name for regulator outputs.

This property is required.

enable-gpios

phandle-array

GPIO to use to enable/disable the regulator.

Unlike the gpio property in the Linux bindings this array must
provide the GPIO polarity and open-drain status in the phandle
selector.  The Linux enable-active-high and gpio-open-drain
properties are not valid for Zephyr devicetree files.

This property is required.

startup-delay-us

int

Startup time, in microseconds

off-on-delay-us

int

Off delay time, in microseconds

regulator-always-on

boolean

regulator should always be on

regulator-boot-on

boolean

regulator should be turned on at startup

supply-gpios

phandle-array

GPIO specifier that controls power to the device.

This property should be provided when the device has a dedicated
switch that controls power to the device.  The supply state is
entirely the responsibility of the device driver.

Contrast with vin-supply.

vin-supply

phandle

Reference to the regulator that controls power to the device.
The referenced devicetree node must have a regulator compatible.

This property should be provided when device power is supplied
by a shared regulator.  The supply state is dependent on the
request status of all devices fed by the regulator.

Contrast with supply-gpios.  If both properties are provided
then the regulator must be requested before the supply GPIOS is
set to an active state, and the supply GPIOS must be set to an
inactive state before releasing the regulator.
