From mboxrd@z Thu Jan 1 00:00:00 1970 From: dsaxena@linaro.org (Deepak Saxena) Date: Thu, 4 Aug 2011 06:49:05 -0700 Subject: [PATCH 04/12] ARM: clps711x: Remove LATCH and CLOCK_TICK_RATE dependency In-Reply-To: References: Message-ID: <20110804134905.GB1019@plexity.net> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
