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,
while the second patch adds the PtP driver itself.

Changes in v2:
- add missing MODULE_DESCRIPTION()
- drop udev event patch
- simplify eitod_to_ns()
- use store_tod_clock_ext() instead of store_tod_clock_ext_cc()
- move stp_enabled() declaration to stp.h
- use s390 instead of 'Z' in clock names
- defconfig symbol should be default-n

Sven Schnelle (2):
s390/time: Add clocksource id to TOD clock
s390/time: Add PtP driver
