/** * i2c_dp_aux_add_bus() - register an i2c adapter using the aux ch helper * @adapter: i2c adapter to register * * This registers an i2c adapater that uses dp aux channel as it's underlaying * transport. The driver needs to fill out the &i2c_algo_dp_aux_data structure * and store it in the algo_data member of the @adapter argument. This will be * used by the i2c over dp aux algorithm to drive the hardware. * * RETURNS: * 0 on success, -ERRNO on failure. */
