From 9e0081d573442e7234355f0a043218d15df03933 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Beno=C3=AEt=20Th=C3=A9baudeau?= Date: Tue, 14 Aug 2012 08:43:07 +0000 Subject: [PATCH] mx31: Fix PDR0_CSI_PODF MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The CSI PODF bit-field used by the previous code for the i.MX31 CCM PDR0 register is actually composed of two bit-fields: one pre-divider and one post-divider. This patch fixes the CCM access macros and the code using them accordingly.
