General informations

Help text

This driver adds support for S390 time steering via the PtP interface. This works by adding a in-kernel clock delta value, which is always added to time values used in the kernel. The PtP driver provides the raw clock value without the delta to userspace. That way userspace programs like chrony could steer the kernel clock.
