Vendor: Cirrus Logic, Inc.

Description

Cirrus CP9314 Buck Switched Cap DC/DC Converter

  compatible = "cirrus,cp9314";
  reg = <0x72>;

  cirrus,initial-switched-capacitor-mode = "2:1";
};

Properties

Properties not inherited from the base binding file.

Name

Type

Details

cirrus,en-gpios

phandle-array

GPIO tied to EN pin

cirrus,initial-switched-capacitor-mode

string

Desired switched capacitor ratio set at initialization. This entry will overwrite
the selection set by the PROG resistor.

Legal values: '2:1', '3:1'

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.

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.
