In which case, the name needs to match the one in the driver: static struct i2c_driver idtcm_driver = { .driver = { .of_match_table = of_match_ptr(idtcm_dt_id), .name = "idtcm", }, .probe = idtcm_probe, .remove = idtcm_remove, .id_table = idtcm_i2c_id, }; So, "idtcm" in this case. How else will it match? -- Lee Jones [李琼斯] Senior Technical Lead - Developer Services Linaro.org │ Open source software for Arm SoCs Follow Linaro: Facebook | Twitter | Blog
