Hello, 
   I have platform which has 5 hw devices and I want single driver to control all the devices. I donot need probe as I know the devices are present and I know all the slave address. The interface for read write is using sysfs and I am planning to put it under hwmon. These all devices are separate chips.

   Can I do this please let me know.


 struct foo_data { 
    struct i2c_client client_data[5]; 
   }; 

int foo_detect_client(struct i2c_adapter *adapter, int address,  
                         unsigned short flags, int kind) 
{ 
     int err = 0; 
     int i; 
     int addrtemp[]= {0x42,0x45,0x46,0x47,0x48};
     struct i2c_client *new_client; 
     struct foo_data *data; 
     const char *client_name = "";
     
      For(i=0;i<5;i++)
      {
           new_client = &data->client_data[i];
           new_client->addr = addrtemp[i]; 
           new_client->data = data; //lets consider it is same 
           new_client->adapter = adapter; 
           new_client->driver = &foo_driver; 
           new_client->flags = 0; 
     
           strcpy(new_client->name,client_name); 
          /* Tell the i2c layer a new client has arrived */ 
          if ((err = i2c_attach_client(new_client))) 
      }
}

Thanks
Kalhan
