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 v3: - drop 'IBM' from clock names - use u128 as return type of eitod_to_ns() - fix calculation in eitod_to_timespec64() 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 MAINTAINERS | 6 ++ arch/s390/include/asm/stp.h | 1 + arch/s390/include/asm/timex.h | 6 ++ arch/s390/kernel/time.c | 7 ++ drivers/ptp/Kconfig | 11 +++ drivers/ptp/Makefile | 1 + drivers/ptp/ptp_s390.c | 129 ++++++++++++++++++++++++++++++++ include/linux/clocksource_ids.h | 1 + 8 files changed, 162 insertions(+) create mode 100644 drivers/ptp/ptp_s390.c -- 2.43.0
