From 0345b51c6a4bfaf6c066b8055d02116432b6a0c9 Mon Sep 17 00:00:00 2001 From: Ben Dooks Date: Thu, 30 Jul 2009 23:23:31 +0100 Subject: [PATCH] ARM: S3C2440: CPUFREQ: Add crystal frequency Kconfig entries. Add entries to select the crystal to select for each different supported board. This information is then available for anything else requiring this, such as the CPUFreq PLL tables.
