Uwe Kleine-König - Nov. 4, 2013, 11 a.m.
While mach/timex.h isn't used for multi-platform builds it still is for
"normal" builds. As there are only three platforms that do something else
than only defining CLOCK_TICK_RATE (and these are probably easy to fix),
deprecate mach/timex.h and drop the corresponding files.

I don't think we can do this (yet): IIRC, CLOCK_TICK_RATE is required
at least for platforms using CONFIG_ARCH_USES_GETTIMEOFFSET (which
is not allowed for multiplatform).

Hmm, I indeed missed some uses, i.e. ep93xx, mmp, netx, sa1100, u300,
ixp4xx and rpc use CLOCK_TICK_RATE (or LATCH). Also
drivers/rtc/rtc-pxa.c uses CLOCK_TICK_RATE. I didn't find that
ARCH_USES_GETTIMEOFFSET implies a use of CLOCK_TICK_RATE though. Did I
miss something?

For now I took the patch out of my next branch and will rework it to at
least let the above listed platforms also continue to use timex.h.

Best regards
Uwe
