Component Type: kbuild config
More info: Drivers that can optionally use the PTP_1588_CLOCK framework should depend on this symbol to prevent them from being built into vmlinux while the PTP support itself is in a loadable module. If PTP support is disabled, this dependency will still be met, and drivers refer to dummy helpers.
Build project: Kconfig (Linux kconfig) (Path: drivers\ptp\Kconfig )
