Subject: [PATCH RESEND 0/3] PtP driver for s390 clocks

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.

Sven Schnelle (3):
  s390/time: Add clocksource id to TOD clock
  ptp: Add clock name to uevent
  s390/time: Add PtP driver
