Without I2C, we get a link failure:
drivers/ptp/ptp_clockmatrix.o: In function `idtcm_xfer.isra.3': ptp_clockmatrix.c:(.text+0xcc): undefined reference to `i2c_transfer' drivers/ptp/ptp_clockmatrix.o: In function `idtcm_driver_init': ptp_clockmatrix.c:(.init.text+0x14): undefined reference to `i2c_register_driver' drivers/ptp/ptp_clockmatrix.o: In function `idtcm_driver_exit': ptp_clockmatrix.c:(.exit.text+0x10): undefined reference to `i2c_del_driver'
