Detailed Description

BC1.2 driver APIs.

Macro Definition Documentation

BC12_CHARGER_MAX_CURR_UA

#define BC12_CHARGER_MAX_CURR_UA   1500 * 1000

#include <zephyr/drivers/usb/usb_bc12.h>

BC1.2 USB charger maximum current.

BC12_CHARGER_MIN_CURR_UA

#define BC12_CHARGER_MIN_CURR_UA   2500

#include <zephyr/drivers/usb/usb_bc12.h>

BC1.2 USB charger minimum current.

Set to match the Isusp of 2.5 mA parameter. This is returned by the driver when either BC1.2 detection fails, or the attached partner is a SDP (standard downstream port).

The application may increase the current draw after determing the USB device state of suspended/unconfigured/configured. Suspended: 2.5 mA Unconfigured: 100 mA Configured: 500 mA (USB 2.0)

BC12_CHARGER_VOLTAGE_UV

#define BC12_CHARGER_VOLTAGE_UV   5000 * 1000

#include <zephyr/drivers/usb/usb_bc12.h>

BC1.2 USB charger voltage.

Typedef Documentation

bc12_callback_t

typedef void(* bc12_callback_t) (const struct device *dev, struct bc12_partner_state *state, void *user_data)

#include <zephyr/drivers/usb/usb_bc12.h>

BC1.2 callback for charger configuration.

Parameters

dev	BC1.2 device which is notifying of the new charger state.
state	Current state of the BC1.2 client, including BC1.2 type detected, voltage, and current limits. If NULL, then the partner charger is disconnected or the BC1.2 device is operating in host mode.
user_data	Requester supplied data which is passed along to the callback.

Enumeration Type Documentation

bc12_role

enum bc12_role

#include <zephyr/drivers/usb/usb_bc12.h>

BC1.2 device role.

Enumerator
BC12_DISCONNECTED
BC12_PORTABLE_DEVICE
BC12_CHARGING_PORT

bc12_type

enum bc12_type

#include <zephyr/drivers/usb/usb_bc12.h>

BC1.2 charging partner type.

Enumerator
BC12_TYPE_NONE	No partner connected.
BC12_TYPE_SDP	Standard Downstream Port.
BC12_TYPE_DCP	Dedicated Charging Port.
BC12_TYPE_CDP	Charging Downstream Port.
BC12_TYPE_PROPRIETARY	Proprietary charging port.
BC12_TYPE_UNKNOWN	Unknown charging port, BC1.2 detection failed.
BC12_TYPE_COUNT	Count of valid BC12 types.

Function Documentation

bc12_set_result_cb()

int bc12_set_result_cb	(	const struct device *	dev,
		bc12_callback_t	cb,
		void *	user_data
	)

#include <zephyr/drivers/usb/usb_bc12.h>

Register a callback for BC1.2 results.

Parameters

dev	Pointer to the device structure for the BC1.2 driver instance.
cb	Function pointer for the result callback.
user_data	Requester supplied data which is passed along to the callback.

Return values

0	If successful.
-EIO	general input/output error.

bc12_set_role()

int bc12_set_role	(	const struct device *	dev,
		enum bc12_role	role
	)

#include <zephyr/drivers/usb/usb_bc12.h>

Set the BC1.2 role.

Parameters

dev	Pointer to the device structure for the BC1.2 driver instance.
role	New role for the BC1.2 device.

Return values

0	If successful.
-EIO	general input/output error.
