Subject: [PATCH 04/12] ARM: clps711x: Remove LATCH and CLOCK_TICK_RATE dependency

From: [email-masked] (Deepak Saxena)
Date: Thu, 4 Aug 2011 06:49:05 -0700

As part of work to remove the global CLOCK_TICK_RATE symbol,
this patch defines a sub-arch local value for use by the
clps711x code.  Once all LATCH and CLOCK_TICK_RATE references
are removed, we will remove all the definitions across
sub-arches.
