NAME

       struct_i2c_board_info - template for device creation

SYNOPSIS

       struct i2c_board_info {
	 char type[I2C_NAME_SIZE];
	 unsigned short flags;
	 unsigned short addr;
	 void * platform_data;
	 struct dev_archdata * archdata;

	 struct acpi_dev_node acpi_node;
	 int irq;
       };

MEMBERS

       type[I2C_NAME_SIZE]
	   chip type, to initialize i2c_client.name

       flags
	   to initialize i2c_client.flags

       addr
	   stored in i2c_client.addr

       platform_data
	   stored in i2c_client.dev.platform_data

       archdata
	   copied into i2c_client.dev.archdata

       of_node
	   pointer to OpenFirmware device node

       acpi_node
	   ACPI device node

       irq
	   stored in i2c_client.irq

DESCRIPTION

       I2C doesn't actually support hardware probing, although controllers and devices may be able to use I2C_SMBUS_QUICK to tell whether or not
       there's a device at a given address. Drivers commonly need more information than that, such as chip type, configuration, associated IRQ,
       and so on.

       i2c_board_info is used to build tables of information listing I2C devices that are present. This information is used to grow the driver
       model tree. For mainboards this is done statically using i2c_register_board_info; bus numbers identify adapters that aren't yet available.
       For add-on boards, i2c_new_device does this dynamically with the adapter already known.
