[PATCH 01/12] ARM: Remove LATCH reference for time-acorn.c

[PATCH 01/12] ARM: Remove LATCH reference for time-acorn.c

[Deepak Saxena]

As part of work to remove the global CLOCK_TICK_RATE
symbol, this patch defines a sub-arch local value
for use by the time-acorn.c file. This is only used
when mach-rpc is built and the tick rate was taken
from that sub-arch's timex.h header.

[PATCH 10/12] ARM: pnx4000: Remove LATCH and CLOCK_TICK_RATE dependency

[Deepak Saxena]

As part of work to remove the global CLOCK_TICK_RATE symbol,
this patch defines a sub-arch local value for use by the
pnx4000 code.  Once all LATCH and CLOCK_TICK_RATE references
are removed, we will remove all the definitions across
sub-arches.

[PATCH 12/12] ARM: Remove mach-*/include/mach/timex.h

[Deepak Saxena]

We no longer use the global LATCH definition to drive
any platform-specific timers so we can remove the
timex.h files from all sub-arch include directories.

We still need to keep an ARM CLOCK_TICK_RATE due to
jiffies.h depending on it to build but that will be
removed in the future once all non-ARM references to
LATCH are also removed.

[PATCH 03/12] ARM: unicore32: Remove depency on LATCH

[Deepak Saxena]

On Aug 04 2011, at 06:47, Deepak Saxena was caught saying:

Obviously ignore this one, this should have been in another branch. :)

This confusing define has bitten me in the past so I'm very happy
to get rid of it. So for ux500, u300 and nomadik:

Acked-by: Linus Walleij <linus.walleij@linaro.org>

Confused...

mach-ep93xx/core.c uses the CLOCK_TICK_RATE to determine TIMER4_TICKS_PER_JIFFY.
Timer 4 runs at 983.04 kHz, this patch changes this rate to 1 MHz.  Won't that
effect the sys_timer?

BTW, it looks like Lennert's patch correctly handled this.

Here's the relevant piece.

Shouldn't this be ACORN_TICK_RATE ?

And also these should all be DIV_ROUND_CLOSEST(xxx_TICK_RATE, HZ)

Ack. Will update all patches and post an updated version with
some other fixes.
