From: Nishanth Menon Date: Thu, 19 Aug 2010 00:39:09 +0000 (-0500) Subject: omap2: i2c: remove redundant header definitions X-Git-Tag: v2010.09-rc1~7^2~5 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=a947f4b68b04fa73d8c862185b8cb7e61abda211;p=u-boot omap2: i2c: remove redundant header definitions Remove the register offset and common defines which are already present in drivers/i2c/omap24xx.h. All of these defines carry the same value even.
