From b63128e81214cc2db2995d690438055c26d213a5 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Fri, 11 Dec 2009 16:16:32 -0800 Subject: omap: Split i2c platform init for mach-omap1 and mach-omap2 Otherwise we cannot limit new mux code to mach-omap2. The same signal names should eventually work for other omaps under mach-omap2. Note that these pins don't need to be OMAP_PIN_INPUT_PULLUP, just OMAP_PIN_INPUT is enough.
