I2C_NEW_DUMMY(9)					      I2C and SMBus Subsystem						  I2C_NEW_DUMMY(9)

NAME
       i2c_new_dummy - return a new i2c device bound to a dummy driver

SYNOPSIS
       struct i2c_client * i2c_new_dummy(struct i2c_adapter * adapter, u16 address);

ARGUMENTS
       adapter
	   the adapter managing the device

       address
	   seven bit address to be used

CONTEXT
       can sleep

DESCRIPTION
       This returns an I2C client bound to the "dummy" driver, intended for use with devices that consume multiple addresses. Examples of such
       chips include various EEPROMS (like 24c04 and 24c08 models).

       These dummy devices have two main uses. First, most I2C and SMBus calls except i2c_transfer need a client handle; the dummy will be that
       handle. And second, this prevents the specified address from being bound to a different driver.

       This returns the new i2c client, which should be saved for later use with i2c_unregister_device; or NULL to indicate an error.
