Hi, these patches add support for using the s390 physical and TOD clock as ptp clock. To do so, the first patch adds a clock id to the s390 TOD clock. The second patch adds sending a udev event when a ptp device is added, so that userspace is able to generate stable device names for virtual ptp devices. The last patch adds the PtP driver itself.
