* Introduction
The aim of this patch set is to add support for PTP Hardware Clocks
(PHCs) into the Linux kernel.
* PTP Patch ChangeLog
** v8
- incorporates Arnd Bergmann's and Thomas Gleixner's comments from v7
- use John Stultz's timekeeping_inject_offset in do_adjtimex()
- adds new syscall clock_adjtime to each arch individually
- cleaned up the CLOCK_DISPATCH mess
- redsigned posix_clock_operations:
. remove compat_ioctl
. flatten clock ops and chardev ops into one structure
. drivers use container_of to get private data
- removed unused and useless code from posix-clock.c|h
- moved posix-clock syscall prototypes into private header
- moved extern declaration from c source file into header
- ptp drivers use container_of to get private data
* Previous Discussions
This patch set previously appeared on the netdev list. Since V5 of
the character device patch set, the discussion has moved to the
lkml.

John Stultz (1):
time: Introduce timekeeping_inject_offset
Richard Cochran (12):
ntp: add ADJ_SETOFFSET mode bit
posix clocks: introduce a syscall for clock tuning.
posix_clocks: add clock_adjtime for arm
posix_clocks: add clock_adjtime for blackfin
posix_clocks: add clock_adjtime for powerpc
posix_clocks: add clock_adjtime for x86
posix clocks: cleanup the CLOCK_DISPTACH macro
posix clocks: introduce dynamic clocks
ptp: Added a brand new class driver for ptp clocks.
ptp: Added a clock that uses the eTSEC found on the MPC85xx.
ptp: Added a clock driver for the IXP46x.
ptp: Added a clock driver for the National Semiconductor PHYTER.
