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.

To do this, let's first split it to private soc.h to mach-omap1 and mach-omap2. We have to keep plat/cpu.h around until the remaining drivers are fixed, so let's include the local soc.h in plat/cpu.h and for drivers still including plat/cpu.h. Once the drivers are fixed not to include plat/cpu.h, we can remove the file. This is needed for the ARM common zImage support.
