9ae6d4935e testptp: Silence compiler warnings on ppc64
When compiling Documentation/ptp/testptp.c the following compiler
warnings are printed out:

Documentation/ptp/testptp.c: In function ‘main’:
Documentation/ptp/testptp.c:367:11: warning: format ‘%lld’ expects argument
    of type ‘long long int’, but argument 3 has type ‘__s64’ [-Wformat=]
           event.t.sec, event.t.nsec);
           ^
Documentation/ptp/testptp.c:505:5: warning: format ‘%lld’ expects argument
    of type ‘long long int’, but argument 2 has type ‘__s64’ [-Wformat=]
     (pct+2*i)->sec, (pct+2*i)->nsec);
     ^
Documentation/ptp/testptp.c:507:5: warning: format ‘%lld’ expects argument
    of type ‘long long int’, but argument 2 has type ‘__s64’ [-Wformat=]
     (pct+2*i+1)->sec, (pct+2*i+1)->nsec);
     ^
Documentation/ptp/testptp.c:509:5: warning: format ‘%lld’ expects argument
    of type ‘long long int’, but argument 2 has type ‘__s64’ [-Wformat=]
     (pct+2*i+2)->sec, (pct+2*i+2)->nsec);

This happens because __s64 is by default defined as "long" on ppc64,
not as "long long". However, to fix these warnings, it's possible to
define the __SANE_USERSPACE_TYPES__ so that __s64 gets defined to
"long long" on ppc64, too.

5345c1d417 ptp: restore the makefile for building the test program.
This patch brings back the makefile called testptp.mk which was removed
in commit adb19fb66e (Documentation: add makefiles for more targets).

While the idea of that commit was to improve build coverage of the
examples, the new Makefile is unable to cross compile the testptp program.
In contrast, the deleted makefile was able to do this just fine.

This patch fixes the regression by restoring the original makefile.

888a36871e ptp: add the pin GET/SETFUNC ioctls to the testptp program.
This patch adds a option to the test program that lists the
programmable pins on a PTP Hardware Clock device, assuming there
are any such pins. A second option lets the user reprogram the
auxiliary function of a single pin.

d94ba80ebb ptp: Added a brand new class driver for ptp clocks.
This patch adds an infrastructure for hardware clocks that implement
IEEE 1588, the Precision Time Protocol (PTP). A class driver offers a
registration method to particular hardware clock drivers. Each clock is
presented as a standard POSIX clock.

The ancillary clock features are exposed in two different ways, via
the sysfs and by a character device.
