ptp now depends on the optional POSIX_TIMERS setting and fails to build if we select it without that:
warning: (LIQUIDIO_VF && TI_CPTS) selects PTP_1588_CLOCK which has unmet direct dependencies (NET && POSIX_TIMERS) warning: (LIQUIDIO_VF && TI_CPTS) selects PTP_1588_CLOCK which has unmet direct dependencies (NET && POSIX_TIMERS) ERROR: "posix_clock_unregister" [drivers/ptp/ptp.ko] undefined!

ERROR: "pps_register_source" [drivers/ptp/ptp.ko] undefined! It seems that two patches have collided here, the build failure is a result of the combination. Changing the new option to 'imply' as well fixes it.
