From 3a8761c0272c961c707e5af2eb0179adf3ef7e14 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Mon, 8 Oct 2012 09:11:22 -0700 Subject: ARM: OMAP: Split plat-omap/i2c.c into mach-omap1 and mach-omap2 There's no need to keep the device related things in the common i2c.c as omap2+ is using hwmod. Split the code to mach-omap1 and mach-omap2 parts and only leave common code to plat-omap/i2c.c. Note that as omap1 only has one i2c controller, we can now remove the old device related macros.
