From bc5d0c89c88df67f92d5d5882c27437379e9e8af Mon Sep 17 00:00:00 2001 From: Eduardo Valentin Date: Thu, 3 Jul 2008 12:24:39 +0300 Subject: ARM: OMAP: McBSP: Prepare for splitting into omap1 and omap2 code This patch transform mcbsp code to use platform data from arch/arm/plat-omap/devices.c It also gets ride of ifdefs on mcbsp.c code. To do it, a platform data structure was defined.
