STRUCT I2C_BOARD_INF(9)              I2C and SMBus Subsystem              STRUCT I2C_BOARD_INF(9)



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 device_node * of_node;
         struct fwnode_handle * fwnode;
         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

       fwnode
           device node supplied by the platform firmware

       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.
