zephyr,usb-c-vbus-adc

Vendor: Zephyr-specific binding

Note

An implementation of a driver matching this compatible is available in drivers/usb_c/vbus/usbc_vbus_adc.c.

Description

This device is used to measure VBUS on a Type-C Port and to
discharge VBUS when needed.

Properties

Properties not inherited from the base binding file.

Name

Type

Details

discharge-gpios

phandle-array

output-ohms

int

Resistance of the lower leg of the voltage divider

This property is required.

full-ohms

int

Resistance of the full path through the voltage divider.

If absent or zero the driver assumes that the upper leg is a
resistance-based sensor.

power-gpios

phandle-array

Control power to the voltage divider inputs.

If present the corresponding GPIO must be set to an active level
to enable the divider input.

power-on-sample-delay-us

int

Duration to delay sampling after enabling the circuitry with
`power-gpios`. In most cases the switched voltage rail will
require some non-zero time to settle to its final value. The
default value of 100us should be sufficient in most situations.

Default value: 100
