USB_BUS_START_ENUM(9)					       Host Controller APIs					     USB_BUS_START_ENUM(9)

NAME

       usb_bus_start_enum - start immediate enumeration (for OTG)

SYNOPSIS

       int usb_bus_start_enum(struct usb_bus * bus, unsigned port_num);

ARGUMENTS

       bus
	   the bus (must use hcd framework)

       port_num
	   1-based number of port; usually bus->otg_port

CONTEXT

       in_interrupt

DESCRIPTION

       Starts enumeration, with an immediate reset followed later by khubd identifying and possibly configuring the device. This is needed by OTG
       controller drivers, where it helps meet HNP protocol timing requirements for starting a port reset.

RETURN

       0 if successful.

NAME

       i2c_add_numbered_adapter - declare i2c adapter, use static bus number

SYNOPSIS

       int i2c_add_numbered_adapter(struct i2c_adapter * adap);

ARGUMENTS

       adap
	   the adapter to register (with adap->nr initialized)

CONTEXT

       can sleep

DESCRIPTION

       This routine is used to declare an I2C adapter when its bus number matters. For example, use it for I2C adapters from system-on-chip CPUs,
       or otherwise built in to the system's mainboard, and where i2c_board_info is used to properly configure I2C devices.

       If the requested bus number is set to -1, then this function will behave identically to i2c_add_adapter, and will dynamically assign a bus
       number.

       If no devices have pre-been declared for this bus, then be sure to register the adapter before any dynamically allocated ones. Otherwise
       the required bus ID may not be available.

       When this returns zero, the specified adapter became available for clients using the bus number provided in adap->nr. Also, the table of
       I2C devices pre-declared using i2c_register_board_info is scanned, and the appropriate driver model device nodes are created. Otherwise, a
       negative errno value is returned.
