[Buildroot] [PATCH v6 1/1] linuxptp: new package

[Buildroot] [PATCH v6 1/1] linuxptp: new package

[Petr Kulhavy]

Add the Linux PTP Project package.
http://linuxptp.sourceforge.net/

The SysV and systemd init scripts start the daemon in slave-only mode on eth0
and synchronize the system clock to PTP.

Signed-off-by: Petr Kulhavy <brain@jikos.cz>
--
Changes v5 -> v6:
	- fix broken SYSV init-script path in makefile
	- use current GIT head with fixed issues instead of the released version 1.8
	- remove patches as they are now integrated in GIT

Changes v4 -> v5:
	- move ptp4l parameters into a config file /etc/linuxptp.cfg
	- add step threshold of 1 second into the configuration to quickly correct large errors
	- add systemd service for phc2sys to sync the system clock

Changes v3 -> v4:
	- rename init scripts to linuxptp
	- use git format of the additional patches
	- use the package name in menuconfig 
	- clean-up the clock_nanosleep patch

Changes v2 -> v3:
	- add patches to fix build issues and enable compilation on all targets

Changes v1 -> v2:
	- rename package from ptp4l to linuxptp
	- add EXTRA_LDFLAGS to the build cmd (suggested by Danomi Manchego)
	- sysV startup script: add restart/reload code, use PID file
	- clean-up empty lines and formatting issues
	- license uses SPDX license code
	- update DEVELOPERS file

Now that your patch has been accepted and applied, it is being tested
by our autobuild infrastructure, and numerous build failures have
appeared:

  http://autobuild.buildroot.net/?reason=linuxptp-97c351cafd7327fd28047580c9e2528a6f7e742b

You should normally have received a daily e-mail with the summary of
those build failures.

Do you think you will get the chance of investigating those issues, and
providing additional patches to fix them?

Thanks a lot,

Thomas
