struct_i2c_driver - represent an I2C device driver SYNOPSIS
struct i2c_driver { unsigned int class; int (* attach_adapter) (struct i2c_adapter *); int (* detach_adapter) (struct i2c_adapter *); int (* probe) (struct i2c_client *, const struct i2c_device_id *); int (* remove) (struct i2c_client *); void (* shutdown) (struct i2c_client *); int (* suspend) (struct i2c_client *, pm_message_t mesg); int (* resume) (struct i2c_client *); int (* command) (struct i2c_client *client, unsigned int cmd, void *arg); struct device_driver driver; const struct i2c_device_id * id_table; int (* detect) (struct i2c_client *, struct i2c_board_info *); const unsigned short * address_list; struct list_head clients; }; MEMBERS
class What kind of i2c device we instantiate (for detect) attach_adapter Callback for bus addition (for legacy drivers) detach_adapter Callback for bus removal (for legacy drivers) probe Callback for device binding remove Callback for device unbinding shutdown Callback for device shutdown suspend Callback for device suspend resume Callback for device resume command Callback for bus-wide signaling (optional) driver Device driver model driver id_table List of I2C devices supported by this driver detect Callback for device detection address_list The I2C addresses to probe (for detect) clients List of detected clients we created (for i2c-core use only) DESCRIPTION
The driver.owner field should be set to the module owner of this driver. The driver.name field should be set to the name of this driver. For automatic device detection, both detect and address_data must be defined. class should also be set, otherwise only devices forced with module parameters will be created. The detect function must fill at least the name field of the i2c_board_info structure it is handed upon successful detection, and possibly also the flags field. If detect is missing, the driver will still work fine for enumerated devices. Detected devices simply won't be supported. This is expected for the many I2C/SMBus devices which can't be detected reliably, and the ones which can always be enumerated in practice. The i2c_client structure which is handed to the detect callback is not a real i2c_client. It is initialized just enough so that you can call i2c_smbus_read_byte_data and friends on it. Don't do anything else with it. In particular, calling dev_dbg and friends on it is not allowed. COPYRIGHT
