Function Documentation

usbc_vbus_check_level()

static bool usbc_vbus_check_level ( const struct device *  dev, enum tc_vbus_level  level  )

inlinestatic

#include <include/zephyr/drivers/usb_c/usbc_vbus.h>

Checks if VBUS is at a particular level.

Parameters

dev	Runtime device structure
level	The level voltage to check against

Return values

true	if VBUS is at the level voltage
false	if VBUS is not at that level voltage

usbc_vbus_discharge()

static int usbc_vbus_discharge ( const struct device *  dev, bool  enable  )

inlinestatic

#include <include/zephyr/drivers/usb_c/usbc_vbus.h>

Controls a pin that discharges VBUS.

Parameters

dev	Runtime device structure
enable	Discharge VBUS when true

Return values

0	on success
-EIO	on failure
-ENOENT	if discharge pin isn't defined

usbc_vbus_enable()

static int usbc_vbus_enable ( const struct device *  dev, bool  enable  )

inlinestatic

#include <include/zephyr/drivers/usb_c/usbc_vbus.h>

Controls a pin that enables VBUS measurments.

Parameters

dev	Runtime device structure
enable	enable VBUS measurments when true

Return values

0	on success
-EIO	on failure
-ENOENT	if enable pin isn't defined

usbc_vbus_measure()

static int usbc_vbus_measure ( const struct device *  dev, int *  meas  )

inlinestatic

#include <include/zephyr/drivers/usb_c/usbc_vbus.h>

Reads and returns VBUS measured in mV.

Parameters

dev	Runtime device structure
meas	pointer where the measured VBUS voltage is stored

Return values

0	on success
-EIO	on failure
