From 98582d9562b4bea6b0eb6e2bfafcd3fab3b60ccb Mon Sep 17 00:00:00 2001 From: Lee Jones Date: Tue, 17 Apr 2012 15:52:26 +0100 Subject: [PATCH] ARM: ux500: Remove unused i2c platform_data initialisation code Now that u5500 is obsolete, u8500 is the only user of the Nomadik i2c driver. As such there is no requirement to differentiate between initialisation values. By the time a new SoC is released, almost all of the ux500 platform will be DT:ed, so we can make decisions based on the compatible property instead.
