Here is V15 of the PHC patch series. I had been a bit lazy in adding the acks that have accumulated since V13, and so now I have added them into the commit message, unless the particular patch changed substantially since the ack.
* Introduction The aim of this patch set is to add support for PTP Hardware Clocks (PHCs) into the Linux kernel. The patch series builds upon the dynamic posix clock work appearing in kernel version 2.6.39. Support for obtaining timestamps from a PHC already exists via the SO_TIMESTAMPING socket option, integrated in kernel version 2.6.30. This patch set completes the picture by allow user space programs to adjust the PHC and to control its ancillary features. * Patches for ptpd on sf.net https://sourceforge.net/tracker/?group_id=139814&atid=744634 3225599 [PATCH 1/3] Convert to POSIX clock API. 3225603 [PATCH 2/3] Adapted to use the Linux PTP Hardware Clock API. 3225607 [PATCH 3/3] Adapted to use the newer SO_TIMESTAMPING Linux API. * PHC Patch ChangeLog ** v15 *** general - allow test program to set system time from PTP HW clock *** ixp46x and phyter packet matching - check packet bounds - handle variable ipv4 header length - replace magic numbers with macros * Why all the CCs? - One driver is for PowerPC, and adds device tree stuff. - One driver is for the ARM Xscale IXP465. * Previous Discussions - [V14] http://lkml.org/lkml/2011/4/18/16 - [V13] http://lkml.org/lkml/2011/3/27/2 - [V12] http://lkml.org/lkml/2011/2/28/53 - [V11] http://lkml.org/lkml/2011/2/23/107 - [V10] http://lkml.org/lkml/2011/1/27/71 - [V9] http://lkml.org/lkml/2011/1/13/65 - [V8] http://lkml.org/lkml/2010/12/31/128 - [V7] http://lkml.org/lkml/2010/12/16/195 - [V6] http://lkml.org/lkml/2010/9/23/310 - [V5] http://lkml.org/lkml/2010/8/16/90 - Thomas Gleixner: Rework of the PTP support series core code http://lkml.org/lkml/2011/2/1/137 - Dynamic clock devices [RFC] http://lkml.org/lkml/2010/11/4/290 - POSIX clock tuning syscall with dynamic clock ids http://lkml.org/lkml/2010/9/3/119 - POSIX clock tuning syscall with static clock ids http://lkml.org/lkml/2010/8/23/49 - Versions 1-4 appeared on the netdev list. Richard Cochran (4): 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.
