From 4d17aeb1c5b2375769446d13012a98e6d265ec13 Mon Sep 17 00:00:00 2001 From: Paul Walmsley Date: Tue, 21 Sep 2010 19:37:15 +0530 Subject: OMAP: I2C: split device registration and convert OMAP2+ to omap_device Split the OMAP1 and OMAP2+ platform_device build and register code. Convert the OMAP2+ variant to use omap_device. This patch was developed in collaboration with Rajendra Nayak .
