NAME

i2c_new_device - instantiate an i2c device for use with a new style driver

SYNOPSIS

struct i2c_client * i2c_new_device(struct i2c_adapter * adap, struct i2c_board_info const * info);

ARGUMENTS

adap

the adapter managing the device

info

describes one I2C device; bus_num is ignored

CONTEXT

can sleep

DESCRIPTION

Create a device to work with a new style i2c driver, where binding is handled through driver model probe/remove methods. This call is not appropriate for use by mainboad initialization logic, which usually runs during an arch_initcall long before any i2c_adapter could exist.

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